Gentlemen,
The PRR GG1 is definitely the correct era for pulling your Tin Plate the 1st one rolled off the GE/PRR production line in Altoona Pa in 1934, the Union Switch & Signal in Swissvale, Pa did proto type work for PRR even before that (1933), man I would love to have a 1934 PRR Green One stripe GG-1 to pull my Tin Plate work trains, a P2 would be way cool with all the yard and work sounds.
I do believe a Tin Plate O Gauge, PRR GG-1 would sell like hot cakes also.
Would place my order and pay in advance.
