A few WD locomotives were built at the Riverside Works, along with Tanks and Aircraft.

The biggest locos that we’re built there were four of the Riddles WD 2-10-0 locomotives. They were sent over to Greece during the end of the war. They were named 101 ‘Broadsword’, 102 ‘Valiant’, 103 ‘Courageous’ and 104 ‘Dracana’ by the Works. As you can see, their names are based on Castle Rock’s medieval past. ‘Dracana’ is the name of the Castle itself. 

During their time overseas, the four WDs found themselves hauling weapons and munitions for their Greek owners. ‘Valiant’ was the first to be destroyed, blown up in an air raid whilst it was carrying tanks to the battle lines. 

‘Courageous’ was second to be destroyed, this time derailed when the tracks in front of it were demolished. In the end it was cut up and presumably made into munitions and armour by the Axis. 

‘Broadsword’ and ‘Dracana’ were all that was left by the end of the war and found themselves in freight work right up until the 80s as Λβ967 and Λβ968. Once they became obsolete, they were dumped with other WD locos and left to rot with no second thoughts. 

The Riverside Works wanted it’s WDs back if they were just going to be left lying around for the rest of time, so they applied to have them removed from the loco dump. 

The request was granted and both locomotives removed from the dump along with a few other WD 2-8-0s by other preservation societies, one of the other 2-10-0s now resides at the North Norfolk Railway as 90775.

‘Broadsword’ now runs in BR colours as 90776 (which will be changed into WD livery by next summer) and can be found pulling heavier trains from the exchange sidings near the Mainline. As for 104 ‘Dracana’, she now resides inside the Riverside Works. Out of steam since withdrawal in Greece, ‘Dracana’ now is a static exhibit that only moves into the main workshops during Wartime events. One day she will be returned to steam, repainted in WD green, but for now that is a distant dream. 

There are five WD 2-10-0 locomotives in total about the whole railway. Three are ex-BR and the fourth is 101 ‘Broadsword’. All except ‘Dracana’ are in steam.

(This is alternate history. I’ve added a little bit of actual history to the story but do remember that the Castle Rock railway is entirely fictional)
