You no doubt know this already Mark, but for the benefit of anyone also interested I have found the below link that gives a great account of Class 47 Falcon:

I'm not much into trains, but that was quite interesting.

A small 280mm diameter on a 12LDA28C in a 47....but there are 12 of them


Which gives Mark a maximum tactive effort of 62,000lbs :y :y

Well out rating the tractive effort at 39,667lb at 85% boiler pressure, of the 9F :'( :'( :'(

And hence why the demise of steam came about...... much lower maintenance, better availability, better fuel economy were all the bonus points for diesel (and even more so electric)

The Uk has no choice but to move away from steam.

Did you know they built a class 47 with twin Maybach engines (as per a Western) and electrical drive (look for Brush Class 47 falcon)...sadly scrapped now, it also had a water scoop to use the water troughs on the mainline to replenish the steam heat boilers water supply.

It was a prototype - nearer in design to a 31 - look at the bogies.

It was TOPS class 53 and was numbered 1200 when purchased from Brush by BR.

2800bhp and was better than a Western (srry Western fans)

Most were   ;D

For anyone working on their combustion engine pistons, the following is an example of a brand new one for a 9F 2-10-0 steam railway engine:



each one of the two cylinders fitted to the 9F's (except the Crosti boiler examples, which are another story!) had a diameter of 20 inches and a stroke of 28 inches, which with all the other specifications of this class gave a tractive effort at 85% of boiler pressure (250lb psi) of 39,667lb's.

This is the 9F, 92212, that is being overhauled on the Mid-Hants (The Watercress Line) Railway at Ropley which will soon have the piston fitted:



These freight engines formed a very successful class right at the end of steam on BR, with 9F 92220 Evening Star being the last steam engine built by British Railways in 1960 at the Swindon ex-GWR locomotive works. Now preserved it is one of nine, including 92212, when I last checked.

You haven't been to Ropley without popping in for a cup of tea, have you? :o

Then again, I was in Kent all weekend. ;D

Just looking for my mate spud in that picture. He's normally employed welding inside a firebox, though, and when he emerges he's well camouflaged!

I've been piston from heights of great significance on more than one occasion - does that count? :-/ :-/

Shame then Zulu that they can't engineer durability and extended effective output!! ::) ::) ::) :D ;)
