I have two Model Power freight cars with rapido type couplers on the trucks ( No.4016 50’ gondola and No. 3419 Tank). I would like to change the trucks to the Micro-Trains trucks and couplers, but I have no idea what one I would replace it with. Please help.
Now, how does one know what prototype truck style to use? I am just beginning to work on a layout, but the time period will be current. Is there a specific truck for modern day rolling stock?
