Beautiful selection here! Makes me miss when the Express' in Liverpool were still working :(

Amazing compilation. How come you just touch the relays without using an insulator stick or something? Sure, maybe the logic is a low voltage, or the relays are insulated, but that's a bit of an unnecessary risk.

Express relays were designed in order to be pushed from the front, and this was so engineers could send the lift to floors for testing. The front plate of the relay is fully insulated from the electrical circuit so it's safe to touch.

@@High-Rise Good to know. Looks like metal to me on camera, so I still wouldn't trust it
