Parts of the Piccadilly Line are getting a multimillion-pound glow-up

Ever find yourself on a tube train or platform thinking about all those behind-the-scenes electrical substations and switchboards? Tbh, us neither. But they’re vital parts of the Underground network – and soon some substations on the Piccadilly Line are getting a major upgrade. 

Construction and infrastructure company Balfour Beatty has just been pledged a hefty sum of £43 million by Transport for London to upgrade substations in Hounslow and Hatton Cross. These makeovers won’t physically change much about nearby stations: instead, the upgrades are a bit more technical, with plans set to include adding things called transformer rectifiers, high and low voltage switchboards and auxiliary transformers. 

In practical terms, the upgrades will make the line compatible with the brand-new, swanky Piccadilly Line trains which are coming into service over the next few years. Remember when they were spotted in Austria?

This is the second contract to be awarded under the ‘London Underground High Voltage Power’ framework, and the upgrades are aiming to increase the stations’ ‘traction power’ and capacity.

The work on Hounslow and Hatton Cross should be underway by the end of this year and is due to be completed in 2026.
