Modern Practice
Nowadays helpers/bankers are often controlled by coded radio signals from the locomotive at the head end of the train, allowing one engineer (driver) to simultaneously control the helper(s) and the train being helped. If radio operation is not possible, electrical control might be used, by way of cables running the length of the train (especially in case of passenger trains), or else the helpers are manually controlled, which is still the usual for bank engines at the end of freight trains in Europe.
