An office block with an entrance next to Aldgate East tube station has installed its own private tube train — as a waiting room.

The Relay Building is a newish block nearing completion at the moment, and sits on top of one of Aldgate East tube station entrances. They are currently fitting a huge sliding glass door which is due to be installed in the next couple of weeks.

But behind that glass wall will sit an old sub-surface tube train in the main entrance foyer. It’s their new waiting room.


The train is moderately significant as well, as it is (a replica of) unit number 5721, which saw service on the special farewell tour run by London Underground as the old C-Stock trains were phased out.

Most of the old trains were scrapped, but this one ended up in retirement sitting next to the very station it would have passed through every day.


The hoardings around the office entrance block getting a decent photo at the moment, but the train carriage is in there, and can just about be seen through the barrier.


Edited — turns out someone has renumbered the train, so the one in the foyer isn’t all that it seems. Which is a bit naughty.

This website has been running now for over a decade, and while advertising revenue contributes to funding the website, it doesn't cover the costs. That is why I have set up a facility with DonorBox where you can contribute to the costs of the website and time invested in writing and research for the news articles.

It's very similar to the way The Guardian and many smaller websites are now seeking to generate an income in the face of rising costs and declining advertising.

Whether it's a one-off donation or a regular giver, every additional support goes a long way to covering the running costs of this website, and keeping you regularly topped up doses of Londony news and facts.

If you like what you read on here, then please support the website here.

Thank you

    Is the third photo an actual photo of 5721 now?

    Isn’t it just the top of the carriage, sliced off from the bogeys and other sub-carriage infrastructure?

    That kind of takes the shine off a bit…

  3. The train pictured isn’t actually the 5721 that ran on the farewell c stock trip. The actual 5721 is in the LT Museum’s collection at Acton Depot. We believe this train is actually a renumbered unit, although we don’t know which train this was originally.

  4. 5721, at Acton Depot this morning. Not in an East London Office.

    I’m glad they didn’t really use a piece of tube history as a waiting room, although it would have been cool if it was actually in a station as a waiting room!
