Caroline Pidgeon, Liberal Democrat Mayoral candidate has called for TfL to get a move on and speed up the signalling upgrade works at Turnham Green Station .
Gathering outside Turnham Green last weekend, Caroline joined local Lib Dem councillors in calling for the Piccadilly Line to stop at the station all day.
Caroline said: "There is huge concern about the slippage of this upgrade. The latest information I've been given is that Transport for London won't even start the signalling upgrade until 2022 and it won't be complete until 2025.
