The Transport for London (TfL) is to sell train and coach seats and other parts of its fleet in an attempt to save money.
The scheme, which was launched at the end of September, has been criticised by train operators, who said it would mean fewer seats on the network and potentially lower prices for customers.
It comes after an explosion at Parsons Green station killed 10 people and injured scores of others in May.
TfA has said the scheme will save the taxpayer £1.6bn over 10 years.
A spokesperson said: “Our new Trains for All campaign will provide the funding for the transport sector to make a sustainable transition to a fully modernised, low carbon, low emissions fleet of modern trains, buses, lorries and stations.”
The TfL has set up a new “train safety” fund, which will support operators in developing their own safety measures to reduce the risk of serious injury or death.
In a statement, the TfA said: “This is the first phase of a comprehensive, strategic plan to ensure that our transport infrastructure works better for everyone.”
The fund will help us to ensure we are able to deliver a modern and safe transport system for the people of London.
