is motor oil is safe on plastic models 

 what the differences ? one of my bachmann 4-8-4 has it and one don't?

i have dcc  gp40 it can pull a 10 car train  with no sweat

i have  few older bachmann freight cars  that have truck  mounted couplers how do i make them body mounted couplers like the newer cars?

why? im staying dc for the rest of the year and i just wanted info on this car
   sound like i a lot of room for it to swing  i don't use my 18 r loop that  much  most of my engine are to big for 18 r

i have  no scenery just two loops of track on 4x8 broad  one loop is 22 and one loop is 18 and i have no clue how big it is 

will that work on 18 or 22   turns
