LT Museum Depot Open Day

[ppppenguin]

Went to the London Transport Museum Depot open day today. I've been before and seen the wonderful collection of stuff that's too big or too odd to go in the main museum. Not everything is labelled and there weren't always volunteers in the right place to ask about things. Very well worth a vist. Next open day is in September.

Some highlights were:

* A demonstration of linocut printmaking using a steamroller
* Bits of the control system from the original Victoria Line trains. These were automatically controlled except for the driver closing the doors. No guard. I think the tonewheel device was part of the speed control arrangments which used various pulses and tones sent via the running rails.
* Switchboard equipment. I think some was a generator control panel from Lots Road and some was a DC switchboard from an unknown depot.

Almost forgot to mention the ride on an RT Greenline bus down to Kew Gardens and back. there was also a red RM doing the trip.

Thanks ... shame I missed it. Love the panel with all the green vitreous resistors, beautifully made, takes me back.

I dimly remember reading an article about the Victoria line when it was brand new. Possibly in Meccano Magazine. I would have been 10 or 11 at the time. There was all sorts of stuff about different pulses and tones transmitted from the central control room to the trains. I found some documentation here:

I notice the MEL Combi Elements used in the panel with the vitreous resistors. I have never seen them with individual metal straps to keep them from vibrating! Transistor/Resistor logic modules - very easy to use!

I wondered what those modules were. I guessed they might be logic, like Norbit. Thanks for clarifying.
