L&YR Class 28 Mogul Experiment 4mm (WSF) RC
REAR MOUNTED CHIMNEY VERSION (RC)
Finer smoother FUD version, WSF/BSF also available.
This is a 4mm scale model of the Lancashire and Yorkshire Railway (L&YR) Class 28 Mogul
Historically George Hughes took the design of a Class 28 locomotive and made some alterations.
It is generally thought that 5'6" wheels were used instead of the usual 5'1" wheels and the running
plate was extended to provide room for a Pony Wheel and a few other tweaks were implemented.
At least one drawing of the locomotive exists but as to whether it was actually built is debatable.
Several email exchanges have been made with the NRM about the drawings so the aim is to visit and purchase the drawing/s and get solid details on the mystery locomotive, as a result what we have here currently is a possible representation of what the engine 'could' have looked like, but currently nothing is set it stone. If the conclusion ends up being different then a Version 2 will likely be made.
The Smoke-Box Door is located on a sprue under the body along with a
spare whistle and 2 different types of buffers that the Class 28's ran with. This gives you the
choice of using either or substituting them with metal ones from other manufacturers without
having to hack them off a buffer beam. The Reverser Rod is located just below the boiler - this
needs to be removed and joined to the left hand side of the locomotive starting at the hole in the
cab sheet and finishing towards the lever in between the front Splashers (Wheel Arches). You
will need hand rail pillars or split pins and 0.45mm rod for the hand rails. To make the accurate
positioning and fitting easier, holes have been slightly indented on the body; they just need
drilling out. Couplings are left for the user to decide based upon preference, utilise the slightly
indented holes on the bottom of the chassis at the front by drilling them out; this is to locate a
home made 'goalpost' from Brass or Nickel Silver rod that is compatible with Tension Lock
Auto-Couplers. To fit the chassis to the body the rear simply slots in at an angle. The front is
fixed via a screw or bolt that in WSF and FUD self taps easily and is all that is needed, a nut can
be glued in place inside the Smoke-Box Saddle if desired.
For the Mogul Experiment the Pony Truck swivels on the same pivot as the fixing hole so when
the Chassis to Body retaining bolt is in position, as long as it isn't forced tight the Pony turns
freely. Several Pony Wheel sizes can be used depending upon how far up you screw the retaining
bolt and 2mm brass bearings can also be added for an optional consideration.
This body shell can be fixed to several Ready To Run (RTR) chassis with a little tweaking,
alternatively a specially designed chassis is also available separately either in 00 or P4.
Please see the Chassis themselves for more information.

Alan Gibson is a great resource

For Motors and Gearboxes, High Level are recommended.
For the L&YR Class 28 and Mogul Experiment, to allow your model to be motorised without having to hack away at the underside of the firebox or boiler as is common with many of kits depending what parts you use, a 'Roadrunner Compact +' Gearbox and a 1220 Mashima Motor from High Level will fit nicely, although it is rather small and may lack power if the trains are too long. If using this combination the gearbox sides will need to be packed width ways with plasticard or similar, these components were used in the research and development trial builds.
EDIT: Future builds have shown that a London Road Models GB4 Single stage Motor Mount (Gearbox) fits better, is cheaper and quicker to build. As with all loco kits the choice is entirely yours though.
For crank pins, hand rail rod/wire and pillars, washers, bearings and other small sundry items Mainly Trains is a good website to visit.
But of course you can use whatever suits your needs and preference best,
the above has been typed out to hopefully aid you should you be new to kit building. The advantage of these 3D printed kits is 90% of the work is done for you, both on the body and the chassis.
Due to printing tolerance issues the whistles have had to be removed. Whistles with printable geometry are now available from SCC also - please look in the spares section.
