1995 Walthers 1995 Catalog features a Union Pacific GP9M on its cover. Walthers introduces its starter basic product category called Trainline in 1995. The former Cox GP9 tooling, first found in the hobby market in 1974, returns as the new Walthers Trainline GP9M. Though the shell's heritage is tooling done for Cox two decades eariler, Walthers improves the model with more complete pilots and a better drive than it had as a Cox offering. The FM H10-44 and EMD SW1 are still in the line of higher end loco offerings and have new roadnames in 1995.
