I have noticed on two occasions, on a large layout, that people have incorporated next to the usual roundhouse workshop, a building with a large high chimney with a track leading to it. (See the one pic below) I don’t seem to be able to find what it is for, any ideas?

I think it's a Faller brickworks or boiler house.

Thanks for that but what I was asking is more the purpose of the building but all the better to have a model to do it with.
So why a brickwork or boilers house near the round table?

Thanks for that.
It had never dawned on me how the turntable was made to turn before electricity. Just great I love the idea and will incorporate it in my plans for the turntable, including smoke for the chimney of course. I think era IV will still qualify for it

I think era IV will still qualify for it In the UK, especially at the smaller loco sheds, many turntables were manually rotated by the crew. Obviously the loco had to be balanced dead centre so that the table could be easily pushed. At larger sheds before electric motors were fitted to turntables, the steam locos generally had vacuum operated brakes, and it was quite common for turntables to be operated by vacuum motors worked from the locomotive's own vacuum ejector or pump connected via a flexible hose or pipe. So boiler houses to generate steam for operating turntables would not have been common in the UK. |

The workshops and the roundhouse had a lot of heavy equipment that needed to be run - this used to be steam driven, and of course later electric. Also, a handy supply of steam could be used to warm-up a locomotive that had dropped its fire. In cold climates steam pipes could also be used to heat outside areas to keep them clear of snow by running pipes in the ground. Here's a static steam plant at the old Eveleigh locomotive workshops in Sydney, which is very obviously built from locomotive boilers: http://www.australianste...36%20class%20boilers.htm Sometimes an old steam locomotive would be parked next to the workshop and used as the static steam plant. I can't find a photo of one right now because I can't remember the German name, but I think it was Faller that made a model of this to put next to a roundhouse or workshop, with an extra long smokestack attached and then steam pipes from the loco into the plant. Maybe someone knows the German name for this? - Herman |

Thank you! That is super hard to Google without the right term - couldn't find it at all. I think it's a really interesting detail for a layout. - Herman |

Kimball, Thanks! I had forgotten Mother M had made a set with the Heizkamin and the lok!  |

Here is a video (narration in German) that shows a number of possibilities for Heizlok "operations": source TheTraintv "At the end of their active time, many steam locomotives are converted into heating locomotives or steam dispensers. At the beginning of the 1990s we observed the Schöneweider locomotives heating the points, were in Stassfurt with 01 024 and in Cottbus with 44 1412. Have fun watching." |

In larger workshops, the water in the water tower was also heated in a boiler that was in such buildings with a high chimney! This saved coal in locomotives that would heat up faster to operating temperature.

My first real car - a Wolseley 6/110 Mk2 had vacuum brakes, with a purple servo warning light when the vacuum for the brakes to work was insufficient. It was bit disconcerting when the lamp went on at 70mph!

It was bit disconcerting when the lamp went on at 70mph! I did my initial driving lessons with my father on the family Wolseley 6/90, the 1958 model that had a floor change. There was a linkage to a column change gearbox. I believe the early versions of the 6/90 had column change but later ones used the same gearbox with a linkage to a stubby gear lever on the right hand side of the drivers seat. It also had vacuum power brakes, which one really needed to stop a vehicle that was a ton and a half dry weight. [edit] corrected car model [/edit] Edited by user 12 February 2022 11:33:18(UTC)

I don’t know much about modern cars but it would not surprise me if the servo-assisted brakes still use the vacuum diaphragm.
The windscreen wipers on my first car were vacuum operated. Vacuum “motors” were probably cheap to make. Electric batteries, charging mechanisms and electric motors were primitive and costly.
The vacuum created by an engine is a cheap means of power. In a steam engine the vacuum is created by the draft in the smoke box and that vacuum was applied throughout an English train to keep the brakes OFF. A lever valve allowed Atmospheric pressure to enter the system to put the brakes ON.
In a carbureted internal combustion engine I think the vacuum is created in the fuel inlet manifold. Maybe the same happens in a fuel injected engine.

Yes, it is caused by the engine drawing air past the butterfly valve, which creates the vacuum. This is why the vacuum is lowest when the foot is hard on the throttle, causing the valve to be fully open, hence the least constriction in the air path. I would expect an injected engine ot be similar, as the throttle still operates a butterfly valve.

Manifold vacuum is highest downdraft of the fuel or throttle controls.
