Hey I am starting off my first serous attempt on making a n scale table ( 4 ft by 8 ft) and i am making a engine repair shop, i am planning on getting a bachmann gp50 and was wondering what the minimum length of the siding can be
My Bachmann GP40 measures 4 1/2 inches length including the couplers. One standard straight track should hold your locomotive by itself. Add an end of track bumper section and this should hold most 4 axle diesel locomotives. Longer is better for more flexibility, but minimum would work. If space is a premium for your diesel shed, add an inch or two for the end of your building. The important thing is starting a layout. Model railroading serves me well as a stress reliever fun hobby. Google N Scale Forums to pull up other blog sites relating to this hobby. Fall and Winter have the most train shows; attend any in your area and you will be glad that you did.
