Building some CR Diagram 11A CCTs.
A bit of stock construction, always a joy to do . In this case a pair of CR Dia. 11A CCTS from the latest “True lines Models “ kit. Historical notes can be found in “ Caledonian Railway Wagons” by Mike Williams, many thanks to Tony Brenchley of the CRA for producing the kit.
Ok, so preamble over, lets have a look at it all. A cast resin body, etches for the chassis and springs and castings in brass and whitemetal for details. 
The body tends to curve inwards at the top, seems resin does this. So first step make a roof that is stiff enough to correct this. A simple structure designed and cut of the silhouette forms a roof support that is strong enough to correct the body curve and support the roof itself. 
Roof in place, its a tight enough fit to just clip in. Body has some holes drilled and the droplight filed out. Oddly these vehicles seem to have had one glass and one wood droplight. 
On to the chassis . This is sprung using a system similar to thet of the Bill Bedford chassis. It goes together accurately. These wre dual braked , so a fair bit of stuff hangs off them. 
Basic painting and with wheels in, it runs freely and the springs do spring. I’ll be interested to see how well it runs on the layout in practice. 
Ok, body next.
