2 NBD (1st Series) - Saloon and van (16) NBD - COMBINED NB PASSENGER CAR AND GUARD'S VAN. A saloon or end platform NB which has had a guard's compartment temporarily added in one end. Due to the temporary nature of this conversion, this vehicle also retains its number in the NB numbering sequence but is classed NBD to differentiate it from the standard NBC and the NAC. The use of the D is recognising the code for guard's vans prior to 1910.
