With recent technology model train operators can now enjoy multiple powered units in front, middle, and end of trains - all powered. This is just like the real trains. Lionel Legacy engines, TMCC, ERR upgrades, and MTH (and others) are able to support this by setting up a "train" where all locos are responding to the controller simultaneously. Front multi-powered locos are possible in transformer controlled system but the locos need to be similar in configuration (motors and gear ratios) to prevent push-pull kicking and bucking.
