Dear readers out there in underground world. I am in the throws of building a 5 inch gauge electric loco of the 'growler' type. So a rough scale of 1/12th Thus I have a control system which bogles my tiny mind but I trust it runs, I have yet to give the loco a full shake down but it is my plan to make a driving trolly to tow with it and I wanted to have a semi accurate controller. I have been steaming up the windows on the stuffed and mounted loco in the transport museum and from the wonderful world wide web for pictures and I am having problems understanding how the reverser key on the controller actually stayed in place. When you consider these and the old SUB units on the southern had a similar look. In the later stock there seemed to be a "cover" over the top of the reverser barrel and I would guess that would keep it in place, but as the plan I have for making my so-called down replica I don't want to be having to watch as it flys off int the trackside undergrowth. while trying to keep it looking somewhere close to prototype. Any help would be good and if you would permit I will keep folk updated as it progresses. ![]()   |

That looks to be a simple drum controller of the tramway type. Any picture of the driver's stance on an ordinary electric tramcar will show you what you need to know.
It's easier to see than to describe, but basically there's a slot to let the handle lift off, but only in the 'off' position.

Yes.
There is a peg on the top of the controller and a slot in the base of the key. There is a gap in the slot which allows the key over this peg when in the off position. Once you move the key to forward or reverse the slot moves over the peg and keeps the key captive.

Our very own Chris W has a closer photo of the controller with key inserted but doesn’t show a cover plate over the key: flic.kr/p/2gGt1nm © Chris W 72 |

Growler?
To my ears Sarah Siddons has a very melodious tone of voice such as befits an electric locomotive of distinction and its diesel locomotives that growl!

Remember Sarah has modern brake handles. She originally had a Westinghouse brake handle and a Gresham & Craven vacuum brake handle. Not sure what types as it was a long time ago that I done stock training on the Met locos! I see from the top photo it has the original Westinghouse brake handle.

Yes the bit where the vacuum handle was to my eyes like a modern edition, the plastic hoses and what looks like a beer barrel looks rather odd but I am sure its for mainline work as well. The 4 TC its drags about must have had some work on it for the railway inspectorate. I am guessing that the driving cabs 4TC are not used much? |

From comments I've read elsewhere the driving cabs are still viable and indeed have been used - but only when a compatible locomotive is attached and that rules out when travelling on LU metals as (as far as I'm aware) neither Sarah Siddons nor any LU battery locos have been fitted with the required components.
Also, re: your comment that I've quoted below, I assume that you are aware of the fitting of the central locking that only allows the passenger doors to be opened when the appropriate member of train staff permits it.

It may not be of much use to you, but your picture at the top of this thread was taken from the same point as one I have had for at least 60 years. It does not show the detail you need, but the layout is a lot "Cleaner". I would guess that the photo is circa 1950-1960.
I've just tried to insert the image, but the system wants a URL.. It's not on the web, but on my PC! Help.
