*6692 *666The bridge was a Hawe truss, constructed nine years ago over a stream and highway .about one thousand, five hundred feet east of defendant’s station at Anamosa, on its line of road running from. Marion to Farley, and was fourteen feet wide, and a few inches more than thirty-four feet in' length. The track over the bridge was curved so that the north rail was five or seven inches nearer the truss at the northeast corner than the south rail to the end opposite, and a few inches lower,- — the track curving to the north, — causing the car® to “shuck” over and lean to- the north in passing over the bridge. The trusses on either side were about one-half the height of a. box car, with timbers held together by long iron bolts, with nuts on the inside. These bolts extended through the timbers about two inches beyond the nuts at the northeast corner of the bridge, and came within fifteen inches of a common stock car standing on the track. This distance would vary with the width of the car, the way it was loaded, and the speed of the train. The bridge was in a valley, with up grades in both directions; that to the east being a quarter of a mile east of the bridge and up a considerable hill, while that to the west commenced at the bridge, and was not heavy. From each extremity of the bridge the *667track curved to the north. In approaching the bridge from the east, it was usual to set the brakes at the summit of the elevation or hill, and loosen them at the foot of the grade towards the bridge. The train on which Lounsbury was employed at the time of the accident consisted of fifteen or eighteen freight cars and a combined baggage and passenger car, without air brakes, and approaching Anamosa from the east. The hand brakes had been set at the top of the grade, as usual; and, as the train reached the bottom, Lounsbury, who was on the cars, near the center, began releasing the brakes as he moved forward. There were two refrigerator cars immediately behind the tender; then a flat car, used for coal, and boxed in, except about two feet on the end towards the engine, with sides and end about two and one-half feet high; and back of this a stock car. The train was moving at the rate of eight to ten miles per hour. After releasing the brake at the east end of the stock car, Lounsbury attempted to go down the iron ladder on the north side of the west end thereof, to the flat car,- — the only way then possible, — - in order to release its brake and report on the engine in event another car was to be taken at Anamosa. When he had swung- over the edge of the car, and had descended about four rounds of the ladder, lie was caught by the end of one of the iron bolts referred to, and permanently 'injured. The court, in substance, told the jury that the -defendant had the right to lay its. track upon such a curve as it might deem best, and to elevate the outside rail, -and that it was not required to conform the bridge to the. curve, or to- lay the track so its center would be in the center of the bridge. See Patton v. Railway Co., 73 Iowa, 310; Tuttle v. Railway Co., 122 U. S. 194 (7 Sup. Ct. Rep. 1166). The one question submitted was “whether the defendant was negligent in placing the truss of the bridge in question as *668near to the track as the evidence shows.” That it did was plainly alleged in the petition, and the jury was instructed, in passing upon this issue, “to take into consideration the question as; to whether at that point said Lounsbury and others, as brakemen, would be required to ascend and descend cars in the discharge of their duties, while passing through the said bridge; and the mere fact that the truss was too near to admit of the passage of the plaintiff, if it was so, while riding on the ladder of the car, would not constitute negligence, unless you find that it was necessary for said Lounsbury and other brakemen, in the discharge of their duties, to be in that position, and that the ordinary use of the road at that place, and the ordinary duty of running trains, would require them to- be on the side of the car while passing through the bridge.” The court thus clearly recognized the rule that, in determining whether placing a structure -along a railroad-track is negligence, the place where it is located, and the purposes for which it is or might reasonably be expected to be used, must be considered. It will not be controverted that a railroad company may erect buildings-, tanks, or other structures for use in the transaction of the business as near the track as the necessity or convenience of the company and its patrons, or the economical use of the road, may require, having due regard for the safety of those operating trains. These -are necessary, and, owing to their location at or near the stations, employes are constantly put on their guard. Nor can the railroad company be said to be negligent in permitting obstructions between stations which do not interfere in any way with the ordinary and usual operation of trains. The evidence tends to show that, -as the trains approached from the east, brakemen, in the discharge of their duties as such, were required to set and loosen the brakes near to and *669over the bridge, and that in doing so they necessarily passed np and down the ladders at the side of the cars, and that the space at the corner of the bridge was so-narrow that a man in using a side ladder at that place would be likely to be caught on the projecting bolts. 'Neither the necessity nor the convenience of the defendant or its patrons required so close a proximity of the rail and truss. It was urged that the bridge was of standard width, and such as is commonly used by all railroads. No evidence in the record tends to sustain this claim. Again, it is said no accident has occurred at this bridge during the nine years of its existence. There was no evidence in support of this contention, and none was admissible. Hudson v. Railway Co., 59 Iowa, 581. The necessity of the bolts projecting between two and three inches beyond the nuts does not appear, though these increased the danger of the locality. Nor can it be doubted that the truss could have been placed at such a distance from the track as to render the place safe for the work of brakemen. That railroad companies are bound to provide a track and equipments which are reasonably safe is not questioned. The truss so near the track, with the projecting bolts, was well calculated to catch and drag down any brakeman who- might be required, in the performance of his duty, to be on the side of the car. Braking was habitually done in that locality and over the bridge, and the defendant was clearly negligent in failing to so adjust its truss and- track and so place the bolts that the work required of brakemen might be performed with reasonable safety to themselves. Many authorities are called to our attention by the defendant. In Illick v. Railway Co., 67 Mich. 637 (35 N. W. Rep. 708), it does not appear that braking was ordinarily required over the bridge, and it seems to have been conceded that the bridge, as originally constructed, was faultless; and the court held that the *670company was not bound to change it so as to conform to the more recent notions of bridge building. In McKee v. Railway Co., 83 Iowa, 622, a brakeman, in order to ascertain what was wrong with the running gear of a freight car, descended the ladder at the side, and, while swinging out to look under, came in contact with the wing of a fence. The court held that, as the accident happened at a place where the employe could not be reasonably expected to be, there was no negligence, saying: “So far as the record shows the accident in question was so improbable, and it was due to causes of such rare occurrence, that the defendant, in the exercise of ordinary diligence, was not required to provide against it.” The same rule controlled in. Koontz v. Railway Co., 65 Iowa, 224, and Davis v. Railway Co., 21 S. C. 104. The Snow Bank Gases turn on the proposition that the dangers arising from the high embankments of snow are such a© are inseparable from the operation of railroads where snow prevails, and are therefore assumed by the employes. Dowell v. Railway Co., 62 Iowa, 629; Brown v. Railway Co., 64 Iowa, 652, In this case the defendant might have accomplished its purpose, and at the same time have protected its employe© from danger. The true rule is thus stated, in Loftus v. Ferry Co., 84 N. Y. 459: “If the defendant ought to have foreseen that such an accident might happen, or if such an accident could have reasonably been anticipated, the omission to provide against it would be actionable negligence.” It is not claimed that to place, the track and truss so near together at every bridge on the road would be negligent, but to do so where the employes are required to go up and down the ladders on the side of the cars, in the discharge of their duties, in the ordinary work in which they are engaged. In this respect it is like the Cattle-Guard Gases. Ordinarily such a guard need not be planked, but, when in switching grounds, this may be necessary in order to *671insure the safety of employes. Ford v. Raihoay Co., 91 Iowa, 179; Railway Co. v. Graves (Tex. Civ. App.) 21 S. W. Rep. 606, is in point. There the brakeman was injured as in this case, and the company adjudged negligent in placing its track too near one side of the bridge, — three and one-half inches nearer one side than the other. As bearing on this question, see 3 Elliott, Railroads, section 1269; Railway Co. v. Welch, 52 Ill. 183; Railway Co. v. Russell, 91 Ill. 299; Kelleher v. Railway Co., 80 Wis; 584 (50 N. W. Rep. 942); Johnson v. Raihoay Co., 43 Minn. 53 (44 N. W. Rep. 884).

4 II. It is insisted that, under the circumstances disclosed in the record, Lounsbury must be held, as a matter of law, to have assumed the risk incident to the condition of the bridge. The evidence that he did not have actual knowledge of the dangerous proximity of the truss is undisputed. Ought he to have known thereof by the exercise of ordinary diligence? If he could have ascertained, by reasonable observation, its dangerous proximity to the track, it must be regarded as an obvious danger, which was assumed by continuing in the service of the defendant. In other words, what a man in law ought', by the exercise of reasonable diligence to know, he does know. Way v. Railway Co., 40 Iowa, 343; Heath v. Mining Co., 65 Iowa, 740; Brown v. Railway Co., 69 Iowa, 162; Magee v. Railway Co., 82 Iowa, 253; Perigo v. Railway Co., 52 Iowa, 277; Wells v. Railway Co., 56 Iowa, 520. Lounsbury was an experienced brakeman, and had been over this road and bridge twice a day for fourteen months. But he had always done so while the train was in motion, and usually when on the running board along the top of the cars. The trusses were only half the height of a box car. The track in both directions from the bridge curved to the north. He testifies that in approaching the bridge he could *672•not see the superstructure from the middle of the cars. When .approaching on a sharp curve, as the witnesses call this, he would be unable to estimate with any degree of accuracy the distance of the truss from the cars or track. He had ridden through on the platform of the combination car, but as the track was on a curve, the distance to the truss would be ever changing. When looking from the north side, the truss came in his line of vision, and he could not see between it and the cars. On the other side the space would be exaggerated, though the south truss was only seven inches further from the track. Much difficulty would be experienced in saying, with the opportunities enjoyed by Lounsbury, whether the truss was dangerously near the track. He had the right to assume, in the absence of knowledge to the contrary, that the place was reasonably safe for doing the work required of him. Situated as he was, and with his opportunities of knowing, it cannot be said, as a matter of law, that he had. knowledge of the dangerous proximity of the projecting bolts to the passing cars. The authorities cited by the defendant are not controlling. In each case the obstruction occasioning the injury had been observed, or was in such plain view that it could be seen by the mere looking. In Illich’s Case the truss was fourteen feet high, and the brakeman had been warned of the danger. The brakeman had seen the post by which he was injured,in Austin v. Railway Co., 164 Mass. 284 (18 N. E. Rep. 209). So, where a brakeman was struck who had not seen it, he was allowed to recover by the same court. Scanlon v. Railway Co., 147 Mass. 484 (41 N. E. Rep. 288). So, where a brakeman was struck by the overhead timber of a low bridge, it was held that he could have observed the danger by looking. Wells v. Railway Co., 56 Iowa, 520. See Williams v. Railway Co., 110 N. Y. 633 (22 N. E. Rep. 1117); Railway *673Co. v. Sentmeyer, 92 Pa. St. 276; Elliott, Railroads, section 2003. The law in 'such cases is not doubted, but in each must be determined on the particular facts shown. Whether Lounsbury ought to have known of the danger is a question, about which men might honestly differ, and was therefore one of fact, to be tried by the jury. Moore v. Railway Co., 102 Iowa, 595.
4 III. Did Lounsbury contribute by his own negligence to his injury? One of the rules of the company, strictly enforced, according to the evidence, was that brakes should be so manipulated that the engineer at all times would have control of the train. These had been set at the top of the grade, and, in order to give effect to this rule, it became necessary to loosen them at the bottom. When Lounsbury, in doing this, reached the brake on the common stock car, he was five or six car lengths from the bridge. His. attention was on his work, which he was doing rapidly. When at the west end of the car, he swung his feet over, turned, and started down the ladder. He did not look ahead, or think of the bridge. He says his attention was absorbed in looking for the hand holds, and for a place to light on the coal flat, which, it will be remembered, had sideboards two and one-half feet high. His purpose and his duty were to loosen the brake on the coal flat, and go to the engine, there to be ready in event a car was to be taken at the station. If he was not charged with knowledge of the danger, he might well give his entire attention to the performance of his duties. True, he might have waited till over the .bridge. Most accidents might be avoided by the possession of sufficient foresight. If he knew of the danger, he ought to have avoided it; but, without such knowledge, he cannot be held, under the circumstances disclosed, to have been negligent in failing to do so. Brakemen are expected to work rapidly, and. necessarily give close attention to what they are at. With *674the train moving at the rate of eight or ten miles an hour, the difficulty in landing on the flat car with the sideboards, and the necessity of preserving a sure hold on the hand holds, it cannot be said, asa matter of law, that he was further required to anticipate and keep a lookout for dangers he knew not of. Indeed, had he looked he could not have ascertained, at any considerable distance from the bridge, the dangerous proximity of the truss. Whether he was in the exercise of ordinary care was a question of fact, to be determined in the usual way. See Whipple v. Railway Co. (R. I.) 35 Atl. Rep. 305; Ferren v. Railway Co., 143 Mass. 197 (9 N. E. Rep. 608).
IV. In an instruction, the court told the jury that “the defendant would not be negligent if it failed to notify said Lounsbury that said bridge was dangerously constructed or maintained.” The defendant is not in a situation to complain of this instruction. There was no claim of having notified Lounsbury. It was not an issue in the case. While erroneous, the instruction was favorable to the defendant, and therefore without prej udice. — Affirmed.
