The 83 members of the 709 Class 0-6-0 tender engines were built by McIntosh from 1895 onwards. They were the original Jumbos, all Westinghouse fitted for mixed traffic duties. Five members of the class Nos 583 to 587 were fitted with condensing apparatus for working the Glasgow underground lines.

The model dates back to the 90s, some of it from a secondhand djh kit, the rest scratchbuilt. Unusually for me it runs on Gibson sprung hornblocks. I noticed that it had developed a squeal when running, time for a bit of an overhaul.

Before and after pictures of the chassis. Better tender pickups cured the squeal.

Back on the track, a view of the right hand side. Westinghouse pump configured as a brake air compressor in the usual CR manner.

A view of the left hand side. This held a second Westinghouse pump configured as a feedwater injector. Hot water in the tanks, or in this case tender, always caused difficulties with steam fed injectors.

Perhaps at some point I might try an improved painting and lining job.

As we discussed in the last blog these were very unusual. There were oddities such as this, but I can find nothing else in regular use.
