G'day Dan - thanks for the response and info. Another question if I may?
I'm trying to get a short ore train take 2 empty ore cars and a caboose from staging to a mine siding, swap them for the 2 full ore cars and return to staging with the caboose of course.
I can get the empty ore cars spotted at the siding but not get the full ore cars picked up for the return trip!
Not sure what settings I need to alter to get this ore car exchange working.
Cheers,
Peter
