The British Rail Class 419 Motor Luggage Vans (or MLV) were battery electric multiple unit cars built from 1951-61 by BR at Eastleigh Works. Each MLV unit is essentially a motorised BG carriage, with a driver's position at each end. Each vehicle has two luggage compartments and a guard's compartment.

By 1963, it was discovered that one luggage carriage was insufficient for the boat train service. Some trains were operated with paired MLVs, which resulted in a shortage of the vehicles. To overcome the problem, six Trailer Luggage Vans (TLV) were introduced in 1968 and kept in use alongside the MLVs until 1975. These were numbered 68201-68206 as Class 499 and were conventional BG carriages, except for having their gangway ends sealed from use.

After withdrawal from normal service, the entire fleet was transferred to departmental service as Class 931 tractor units. All but two of the units have been preserved.
