ok, here is the deal. i am modelling 1950's era with land like that of WV and PA. i have some cheap locomotives and would like to invest in a quality locomotive for my mainline. i really like the look of the Alco RS-1 and the RS-11 as well. i have not been able to find many of these other than atlas (which seems limited). anyone have any ideas on similar models or others that my fit my bill? i am looking to spend around $100 and am running standard DC. also, due to space constraints, the track has a 15" radius, so the shorter the better! thanks for any advice!
