Locobase 9551 shows the passenger-type D class that came from Phoenix Foundry in 1887. They were preceded by very similar freight locomotives that used the same boiler but smaller drivers in an all-adhesion layout. The last of these small goods engines went out of service in 1944.

Using the same firebox as the New A and Y classes, the X classes sported bigger boilers and drivers that undoubtedly made them useful as dual-service locomotives. The last of these was scrapped in 1920.
