Carriage 117 is at the stage where there are seemingly no end of small jobs to finish it off, such as the various bits and pieces which live beneath the frame.
It starts off simply enough with a couple of basic boxes which I knocked up in a spare hour the other night.
These will have to have various bits of pipework, large and small, connected to them.
The larger one, I believe, contains the diesel-powered carriage heater and the smaller one is the fuel tank associated with it.
I am always open to correction, however.
