Product Description

GWR Tadpole, Diagram S4 - ​Chassis (Part 1)


These 6-wheeled 4 plank open fish wagons were built between 1887 - 1888 originally as broad-gauge convertibles. However, In 1892 they were converted to standard gauge and numbered between 42764 – 42799. The fish would have been packed in ice, in either barrels or crates and due to the perishable nature of the cargo the wagons were built to run in passenger trains at express speeds.

This Kit depicts the wagons in their standard gauge form.

Initially these wagons would have been in the standard goods wagon grey but were repainted the brown vehicle livery around 1913 when they were renumbered 2009 – 2044 in that list.

My Tadpole kits comprise two parts, a Chassis (Part 1) and Body (Part 2 which are designed to clip together.

This chassis (Part 1) has been designed to use HORNBY R8264 14.1mm Coach Wheels with "Romford" 2mm plain or shouldered brass bearings (neither supplied). I would recommend removing the flanges from the centre wheel set (unless your points and layout have very shallow curves).

On some prints, I have found that the brass bearings are a very tight fit so I would recommend that the bearing holes are cleaned out with a fine sharp object (pin) to ensure there is no dust from the manufacturing process.

The chassis is provided with NEM coupling pockets.

To complete the model, you will need the following:

Part 2 Tadpole body of your choice,

Buffers, wheels, couplings, paint, and transfers.

I would also recommend adding weight to improve running.
