Painting the boiler cladding.

Many coats of paint and lots of rubbing down between coats will give the deep blue finish required.

Dennis inspects the work so far.

The delivery pipes from the mechanical lubricator.

Just look at the quality of this workmanship!

Exhaust injector steam pipe

This copper pipe, seen here running back towards the grease separator, supplies exhaust steam from the cylinders to power the exhaust injector, which sits close to rail level under the left side of the cab.

The exhaust steam supply to the exhaust injector.

Seen facing the front, the odd rectangular cross-section is due to having to squeeze the pipe past the inside cranks on the front driven axle.

Looking towards the front of the engine.

From left to right: Part of reverser mechanism, exhaust steam pipe, big end of left inside cylinder crank, Walschaert valve gear eccentrics, big end of right inside cylinder crank, reverser mechanism.

Drain cock on right outside cylinder.

Pair of draincocks on outside cylinder.

Actuated from the cab, these allow the egress of condensed water from the cylinders. If water builds up, the piston can 'hydraulic' and smash the end of the cyslinder casting open.

Train Protection Warning System, reverser and (much older) GWR safety system - the ATC bell.

The TPWS, starting at the cab.

The TPWS sensor will sit on the shelf just behind the frame.

The shelf for the TPWS.

This essential piece of modern safety kit will be hidden here so that the aesthetic appearnce of the engine is not altered. The only external clue to the TPWS will be the cable conduit running down the right side of the engine.

Similarly, TPWS sensor at rear of tender.

In the days of steam, a single ATC/AWS unit was possible under the cab. Now with track layouts based on trains with cabs at the front, sensors must be at the extreme ends of the engine.

Tony and Peter working on the lubricator pipes.

If anybody out there recalls microbore central heating, or having to rebuild a car's hydraulic brake system then you will know what this job is like - only the scale is different.
