New trains on the Piccadilly line will allow an initial increase in peak services with the existing signalling from 24 to 27 trains per hour.
A signalling upgrade would provide the capability of up to 36 trains per hour on the core section of the line enabling up to 18 trains per hour on the Heathrow branch. Piccadilly line peak services to Uxbridge are expected to remain at 8 trains per hour as completion of the current 4LM signalling upgrade will enable a combined 20tph peak service frequency between Uxbridge and Central London with faster journey times on the Metropolitan line from 2023.
However, plans for further service enhancements are on hold as the signalling upgrade is currently unfunded. It is vital that the next agreement with Government provides long-term sustainable funding that enables Transport for London (TfL) to properly support the economic recovery of the city and the country as a whole, and the delivery of its planned modernisation programmes. Discussions about this will continue over the coming months, and I hope I can count on the Assembly to support me in securing a settlement which is reasonable and fair for Londoners, and which will safeguard TfL’s future
