I decided to try a crazy idea,since the doppelstock 766.2&767.2 are cab cars could you use them as cab cars for the db br 101,Yes you can(now there are a few minor issues with not being able to use the pass thru car to car doors plus the open side car doors opens opposite doors on each type of coaches).but the controls work almost perfectly but both locos will end up with a driver depending on which cab your in(but you will have the control instead of the ai driver) .Doing this requires some route with switching track space to work with plus you might need to get rid of the extra loco if you don't want to use it.Look this is a limited use option but the point is the db br 101 with it's ic coaches are cab car capable and this suggest a cab car control system must have been built in for this to work,i think the cab car was being worked on and got axed before it was finished.
