A judgment of nonsuit, entered by the court below, is here the subject of review. William F. Essen, son of the plaintiffs, and a draftsman in the employ of the defendant, the city of Philadelphia, was on May 8, 1907, sketching a safety device of the Philadelphia & Reading Railroad Company for the city of Philadelphia. It was work that he had been directed to do for his employer. While doing it, he stood on one of the tracks of the railroad company, was struck by an express train, and was killed.

The safety device, a semaphore about 24 feet high, stood on the side of the platform near Ninth and Spring Garden streets. There were but two tracks at the place of the accident, and there was a platform on each side of the railroad. There is no evidence to show that *415the sketch could not have been made on either platform, or that the deceased’s duty required him, in the performance of his work, to take a position upon the railroad tracks, or that any representative of the city had reason to believe he woidd take such a position. ’Consequently there is no evidence of negligence on the part of the city in failing to warn him of the approaching train. Indeed, he heard the warning whistle of the train, saw the train coming, and, instead of going to the platform, stepped from the track alongside the picket fence between the two tracks, in which place he stood when he received the injury that resulted in his death an hour or two later. The burden was on the plaintiffs to show negligence on the part of the defendant. It seems that the unfortunate man was himself negligent in unnecessarily assuming a dangerous place for doing his work, and in taking his place by the side of the picket fence when the train was approaching him. However that may be, it is clear that no inference of negligence on the part of the defendant can he properly drawn from the facts presented.

The judgment is therefore affirmed, with costs.
