Powering up a 59TS DM

[liverpoollou]

I've seen this done at Mangapps a few years ago to an R Stock DM.

There was a shed lead plugged in to the DM receptacle which was then attached to what I believe was a 240v AC - 630v DC inverter, am I right or was it something else. The power to the DM was enough to work the lighting and supply juice to the Guards panel, air was supplied using a small compressor so the doors could be operated.

Any advice would be welcome.

Seems a wierd way to do it. I've not heard of a 230v - 630v inverter (not to say there isn't one, though)

On a 59 stock, the Guards circuits and emergency lights need 50v DC, the fluorescent lights, 115v AC. These are normally supplied from the MG with the 50v from the battery as backup (no fluorescent lights).

Did the car run normally off 630v traction current at other times? or was this just a single car used for odd things but not motored?

If so, then there is probably no MG and that jumper box wasn't getting 630v at all and was perhaps just getting 50v DC to the car (inverted to 115v AC for the lighting). With the connections from the jumper box modified accordingly. If it was a standalone car, then anything could have been done to modify it to suit requirements.

It was about 15 years ago I saw the R Stock at Mangapps.

I'm sure the guy said it was an inverter from mains to 630v DC, not enough to power the traction motors but definately had the lighting on and the doors operating.

The 59TS is at Suttonhall Railway DM 1305 ex Northern Line, can't work out why there is only one Guards panel though?

[Nortube]

It could be true, especially if they had other 630v equipment that they wanted to power up elsewhere at other times. There may be similar equipment generally available for testing 630v equipment.

It would have to run the MG so that the MG 630v Motor could then turn the 50v DC Generator to provide the 50v DC for the circuits and lighting (or 50v DC and 115v AC on 59 stock). That also means, of course, that the MG would have to be in a fully working condition. I'm not sure how much current an MG draws, but I'm not sure if an ordinary 13A / 240v supply would be enough to run the MG. Higher 240v current supplies are usually supplied from a fixed source (e.g. directly wired rather than plugged into the mains).

avoid 630v! You would need to rectify it of course back to DC, but even the MG would need quite a hefty current. Avoid at all costs! 59/62 TS is different to R stock. As Nortube states, the control circuits are all 50v DC, powered from the batteries under the transverse seats. Charge these up, or if they have had it as I would expect, replace with four "leisure batteries" in series (as used for caravans, etc). You will need to isolate the original supply from the MG equipment as it probably wouldn't like a back-feed. For air supply, connect a suitable compressor (with relief valve!) to the main line at the trailing end, blank off the train line, and doors, brakes, etc should all work. The fluorescent lighting is a problem, as in real life it worked at 115V, 850Hz. Connecting a building site 115V transformer won't work unless you change the starter/ballasts to correct ones for that voltage and frequency. There is one set per light, located behind the adverts. Be very careful disposing of the existing components as they contain some very nasty substances that will need dealing with properly. You will need to find a suitable point to connect this AC feed probably at the jumper cables. On that subject, you will of course need to make various connections to get stuff to work like pilot lights, bell, EP brake, etc, so that the car thinks the rest of the train is still attached. Hope this helps.

Wow! Much more complicated than at first seems.

I'll pass this information on and thank you both for your replies.

A great Forum keep it up.

Lou.

OK Lou. If this is a serious project I can try to help as I have done it! I have all the drawings etc. I know 62 TS best but 59TS is basically the same, except in the MG area (62 TS have MAR not MG). Some cars were modified in later life, if there's only one guard's panel there may be more digging required, I believe most of my drawings etc are "as built". PM me if you need to discuss.

I think you'll find this is the DM in question.

[neilw]

thanks for that. I know its "other half"

I've picked this up and sent your reply to Suttonhall Railway, we'll see if they want some help. Would look good with the lights on and doors working.

With regard to the R Stock, it was owned by Mick Northfield who also obtained something red from the old Woolwich Museum at the same time as I saved the Ongar Lever Frame. There is/was something red at The Pump House Museum in Walthamstow.

OK, thanks, I'll wait to see if someone gets in touch.........
