Some locomotive classes such as the WAP-5 and WAP-7, as well as the WAG-9, have controls in the cab that can 'lock' the train to travel at a certain speed (the speed at the time the control or button is set). The button is known as the 'BPCS' button. The computerized loco controls then manage the tractive effort and braking effort and attempt to keep the speed to within +/- 2km/h of the desired speed. In this mode, the driver does not have to do anything further except to respond to the alerter system (see below) within the stipulated intervals, and to use the horn as appropriate. Older locomotives without computerized controls do not have any such provision for 'cruise control'.

I’ve heard that some locos have ‘cruise control’. What does this mean?
