MOTW - Caernarfon Castle

I’m returning to the locomotive fleet this week and the WHR’s main passenger diesel ‘Caernarfon Castle’.

This is one of a pair imported from South Arfrica in the 1990’s and has retained its original, very continental-style GRP bodywork. (The second machine, which had been given a modified cab during its life in Africa, was selected for a radical rebuild to fit the FR loading gauge and became ‘Vale of Ffestiniog’)

Our model’s built from a Worsley Works ‘scratch aid’ kit. Allen’s etches provide for the bulk of the bodywork leaving you to complete the finer detailing.

It’s powered by a chassis from a Farish Class 90 chassis.

One of the main challenges with modelling the WHR & FR ‘Funkey’ locomotives is the bogies which are very tall, with the side frames extending well above the top of the wheels. This is a problem in 009 when you’re using a N gauge chassis which are mostly built around a big metal block housing the motor and drive to the bogies.

Simply fixing false Funkey side frames onto the N gauge bogies won’t work because they will foul on the metal chassis block and won’t swivel!

Our solution has been to divide the bogie frame in half, so the top is fixed to the metal chassis block and the bottom section, with the axleboxes and springs etc, is bonded to the N gauge bogie and only this lower part swivels.

Other extra details added to the basic body kit include the handrails at each end of the loco and the large headlight jewels.
