Steam Up! - the Tower Bridge Engine

Some more photos of the Tower Bridge steam engine, used during WW2 to lift the bascules of Tower Bridge, at Forncett Steam Museum. This engine was made and fitted in 1941 when the installed engines were removed for safe keeping, incase of being destroyed in an air raid. Everything else could have been replicated, except the steam engine, of which, I think, there were two.

The high pressure cylinder:

Hydraulic cylinder top. These are used to do the actual lifting (as I understand it)

Starting it up: the owner going through the starting procedure:

The cranks, the con-rod slides, and the flywheel:

The nameplate:

The flywheel, counterbalance, and belts:

I hope these prove interesting, and that you enjoy them. All comments very welcome as usual.

Thanks for looking.

A bit that I found on Wikipedia: During the Second World War and as a precaution against the existing engines being damaged by enemy action, a third engine was installed in 1942: a 150 hp horizontal cross-compound engine, built by Vickers Armstrong Ltd. at their Elswick works in Newcastle upon Tyne. It was fitted with a flywheel having a 9-foot (2.7 m) diameter and weighing 9 tons, and was governed to a speed of 30 rpm. The engine became redundant when the rest of the system was modernised in 1974, and was donated to the Forncett Industrial Steam Museum by the Corporation of the City of London

Re: Steam Up! - the Tower Bridge Engine

Nice set Keith. I had a look around the "works" in Tower Bridge many years ago, fascinating place. If I remember correctly the steam engine was used to charge a hydraulic accumulator which did the actual work. I have some slides somewhere, I'll have to dig them out and have another look. A very wide angle lens is definitely helpful, I think I had my 21mm Zuiko at the time. Steam engines in general are very photogenic!

Thanks. I was so busy taking photos that I didn't look at the diagram on the wall! I like them when they are exuding steam - but this one didn't let even a wisp loose. Big engine, and difficult to photograph; you'd need to get up high to see it all in one go.

Re: Steam Up! - the Tower Bridge Engine

I love all this old historic machinery you have in the UK. It speaks of an earlier age of great British engineering. I reckon I could get high on the intoxicating aroma of oil !
