As many will know I've been in Trainz for quite some time, over two years. I've driven in cab mode before, but when running a train that requires mid-train/rear end helpers, are these engines controlled by a separate driver in Trainz or are they under the control of the engineer up front? I know this is automatic when in DCC mode, but the for the particular train I want to recreate in Trainz I would prefer to drive in cab mode. Anyone be able to help out here?
