This morning at Leicester I observed two Permanent Way vehicles (perhaps Plasser and Theurer tampers or rail grinders, or other such styled machines) coupled together working a move around the avoiding line. It sounded as if both vehicles had their engines running, and I can't imagine one would be able to ahul the other - but I don't know what form of multiple working they are capable of.
Does anyone know which machines are capable of working in multiple, if any?
