The tenshodo motor bogies are a simple fix to an aluminium floor that slides onto channels in the body side, simple but very effective. The centre unit articulates around the bogie and arounrd the centre body section. This allows the model to traverse sharp radius curves, although this feature is not required on Round Trees Sidings.

The metro cars have flush glazing designed in a CAD programme linked to a milling machine that produces accurate shapes in 2mm perspex. Once the three different sized windows had been drawn, perspex was placed under the drill head and the computer was politely asked to produce the correct number of metro windows. They are so accurate in shape they are a snug fit in the window aperture and require no glue!

Next stop Regent Centre. (The figures are a "100" pack from Preiser, batch painted one Sunday afternoon.

The working bits. Articulation is even up and down as well as side to side, giving some very smooth running.

Seats and some passengers.

The completed cars.

ready for action!

Close up of the CAD windows.

All complete and ready for a public launch on the EM Society test track at Bletchley - TRAMS - do these steam modellers know anything?

The Dave Alexander metro kit comes in a very sturdy box with all components carefully labelled and packaged. The instructions are very comprehensive and easy to follow.

The main body for each car comprises two sides, nose and roof. These items were glued with araldite.

The metro on a trial run, just to make sure it worked. A difficult task was to re - guage the tenshodos.

No glazing!

Pantograph works and the careful weathering on the roof was sprayed after an hour standing on a footbridge observing the real thing.
