One item of my rolling stock that raises the most questions when I exhibit Fisherton Sarum, and is also one of the most common search terms that readers of
my own blog have used to get there, is in connection with the Bulleid Leader. I will not go in to the whys and wherefores of the prototype as there are enough books and online references, such as the Semg website here or dare I say it Wikipedia here although a few myths about it can be seen to be perpetuated such as that the initial intention “was to replace the aging fleet of M7 class tank engines†when in fact it was to have the same route availability, which is not quite the same thing!
For my own 4mm model of Bulleid’s unconventional ‘Leader’, I utilised a kit of parts from
Golden Arrow Productions. A limited edition ready to run model of this unusual prototype is available but I obtained from them a kit of bits so I could do my own thing when it came to the chassis arrangement etc.The body is one piece resin casting, with additional castings for the ashpan and steam reverser. Being resin the casting is quite thick which is slightly more evident around the windows and is one of the reasons why I did not try and model the roof vent shutters in the open position. Lamp irons and handrails etc were also added.
White metal parts make up the power bogies and I have used
Markits wheels and axles The power bogie is designed to use a LH19 double ended motor with 40:1 worm and gear drive to two of the axles on the bogie. Unlike the Golden Arrow RTR version that is supplied with one powered and one trailing, I chose to make two identical powered versions. Initially power is collected from opposite sides at each bogie with a single wire between the two, I added additional wire wiper pick ups to each bogie (allowing them to be independent units, useful when testing) and ran a pair of wires between each bogie.
