Occasionally - very occasionally - a driving engine will fail. A set can quite happily operate with an engine switched off with only slight reduction in acceleration (in an 8-car set with one dead engine you'd still have over 85% total power). If you're lucky enough to find such a car, you're in for a very much quieter ride.
However, the guys in Drogheda seem to keep them running reliably, so it doesn't happen too often.
