don't know ...
i run one train to the east on the inside loop ...
then i run another train to the west on the outside loop, i can easily do this as i select the crossovers to not change one loop for the other, in other words two seperated loops ..
i then run logging on a siding with another loco ...
and finally a fourth loco on another [mining] siding to pick up or drop off ore cars ..
and then a fifth loco on a small siding to drop of logs at the sawmill ..
all this is with a mrc system [using the recall button]
