This video has some really detailed shots of reconstruction immediately after liberation in northern France. There are some really rough back yard repair methods. Check out the filling of a boiler with buckets at 21:39. Bet you never did that before!

I used a cattle sprayer for seven years. Does that count ???

Watch the film The Titfield Thunderbolt! A bucket brigade is a major scene in the film.

The loco being coaled at 21:11 looks rather like a GWR Dean Goods 0-6-0 as some of them ended up in War Department service in WW2, though it has gained a large air tank on the running plate.

I know, but here they are filling the cold boiler through the safety valve manifold.

Was that a Mamod tractor you were filling?

No Sir --- I had a Porter Forney. Those were the days. It would take all day to gather enough dead wood for a fire, and many trips to the well to fetch water. It was HARD water, so I treated it with CALGON. The cattle sprayer was also used for fire protection and boiler washes, I had to do a washout every time I ran her. No water supply in the enginehouse, as you might imagine. You young kids have it easy these days....

I've got to get my slide of the bucket brigade coaling RDG 2102 in Kent, Ohio in 1977 scanned for here at some point, just to prove it happened.
