Engine shed facilities layout

Postby TimberSurf » Wed Mar 29, 2017 8:02 pm

I find myself at the point I have a turntable and twin track engine shed and track down, but my lack of real railway knowledge now puts me into a dilemma!
I don't know were to put other items, as I don't entirely know the morning/evening procedure. I want a water tower, coal loading and watering point and ash pit and maybe maintenance pit.
But what is the sequence of operation overnight? Which would then dictate the placing of these items?
If I make a stab with a list, can someone rip it apart and re-order please:-
PM
1. Drop ash in Ashpit
2. Fill tender with water while still in steam?

AM
3. Fire up to steam
4. Fill coal in tender under hopper/tower
5. Lube engine
6. Inspect on maintenance inspection pit
7. Clean engine (while firing up?)
8. Rotate engine for departure

When we have determined the correct order, we can discuss if my current layout plan can work (not completely fixed as not yet ballasted)

Hi Timbersurf

I believe the order would be -

PM
1. Drop Ash
2. Fill Water
3. Fill Coal
4. Rotate to required direction

AM.
5. Fire up would be done by firelighters
6. Clean by same
7, Inspect, lube sand etc by crew

Have a look on youtube at 'On The Shed' Part 1 and 2 by LMS, this might give you the ideas.

Hope that helps.

Mac

The video says it all! Thanks Mac

"On the shed"
PM
1. Drop Carriages
2. Rotate
3. Fill water
4. Fill coal
5. Ash pit (smoke box then fire)
6. Inspection pit (remove ash from pan)
7. Reverse to shed
8. Driver leaves tools and writes report

AM
9. Steam raiser fires the engine
10. Engine cleaned
11. Driver checks and lubes
12. Collects coaches

So returning home, TT first, then water and coal (either way), then ash and pit, then shed. Morning straight out.

Not neccesarily, a lot of sheds had some of the roads accessed by the turntable and there were always roundhouses where every loco arrived and departed via the turntable.
All other operations would have been done in the stated order but the turntable operation would have been done at the most convenient.

This seemed quite a logical arrangement (GWR)
Image
Froom: http://www.davidheyscollection.com/page21.htm

Top => Bottom coal stock sidings, coal ramp, loco coaling, ash wagon siding departure line from turntable (with asphpits, I'm guessing)
Loco shed lines. Carriage sidings.

Getting locos off shed in a rush hour would not be limited by turntable occupation.
But if you have two engine sheds then one beyond and one alongside might serve: the place expanded!

That's another hour gone following links! :wink: interesting stuff and a nice compact shed layout if you leave out the sidings at the top.

Looking at the photo further down the referenced page and thinking logically, the ash pit would almost certainly be on the coaling road. This would avoid blocking the turntable access and allow a logical flow through the facilities. Drop fire and rake out smoke box, coal, water, turn and then on to shed.

Cheers

Seems logical.

Just noticed: if those top sidings are for coal, the yard loco (home on the little turntable spur?), fetching some, will be at the wrong end of the rake for delivering them to the coaling stage. Having to run-round via leaving them on the coaling road seems a little clumsy, but maybe that was a quirk produced by lack of space? Alarm call of a morning: the day's coal going up the bank.

I suspect a lot of squashed-in or expanded depots had less than ideal track layouts.

Chris

So lets work out the perfect principle, then from that, bodge it into the space we have!
There are two principles
1. Series - production line in sequence - but if everyone turns up at the same time, you end up with a queue!
2. Parallel - 1 road for each activity - allows freedom to swap order if one road is in use - downside even when empty, lots of shuffling between roads
I may have to create some diagrams! :D

Would that be the ash pit between the coal stage and the turntable?

Actually on reading the caption on the linked page it says it was an inspection pit but it looks a little shallow however on this page http://www.warwickshirerailways.com/gwr/gwrls2200.htm I think it confirms it is the ash pit.

Certainly would be. The first photo shows it nice and clean and the second shows lots of ash around the area.

I have seen photos of ash pits with small bucket cranes to help load the ash into adjacent wagons,
but this might have been in the "You wuz lucky" class rather than standard, or a thing of regional differences.
