#OnThisDay Earl's Court Control Room signals its last train. In its heyday the room controlled most of the District & Piccadilly Lines; a hive of activity. Latterly it has only controlled Fulham Broadway to Putney Bridge, I was lucky to return last month on a @BLSfixtures tour

At the closing of #Nexus2025, I explained how Luxembourg leads the way in building #AIsolutions for public good through initiatives like #LLM4GOV and #4LM. AI is only as powerful as the data and compute supporting it. That’s why our national strategy weaves together #AI #data #quantumtechnologies.

Hitachi Rail has delivered the most complex phase of TfL’s 4LM upgrade at Neasden Depot, integrating new CBTC tech with legacy systems. It’s a major step in boosting speed, safety, and reliability across 40% of the London Underground network.

I expect they want the 4LM upgrade finally finished and in the bag before adding those, which will surely happen.

It was more of a post about a problem with an information system that gave a 4LM explainer as justification for the passenger facing problem, rather than a signalling deep-dive (I expect LonRec archives have that aplenty).

But thanks nonetheless!

Legend has it that in the 1970's in Mt Isa when the local station 4LM closed down at midnight, people used to leave their radios on and be woken up at 5am when the station started. One announcer meant to play Misty Mountain hop, but instead played Black Dog, and the whole town nearly shit themselves
