My wife's grandfather worked for the PRR as a conductor. Here is a photo of him taken in 1910 in Brownsville PA. He is on the far right...looks like they were doing some street running (lol). The is art work is his as well from around the same time. It is a reverse glass painting of horse shoe curve, notice the 4 track main. It has some paint loss but I am hesitant to take it to someone for repair for fear of further damage. It hangs proudly above my layout. I also have his PRR lantern.
