I am aware that Bombardier failed to deliver trains for use of the Gospel Oak to Barking line and the Chingford to Liverpool St line on time in 2018. Please provide percentages of the number of trains Bombardier has delivered on time between 2013- present day broken down by year and providing details of the lines the Bombardier trains were planned to run on.

Bombardier Trains Delivery

Answered By:

The delivery of new rolling stock is a complex matter with many deliverables to be considered to ensure that stock is reliable and safe for passenger operations.

With the increasing amount of technology used as part of new rolling stock trains go through various stages of acceptance and even if a train is delivered on time it usually requires thousands of hours of fault free running before it can be considered for passenger operation.

Transport for London (TfL) has ordered three trains from Bombardier over a number of batches. These include the Class 710, the S-Stock, and the Class 345.

TfL has worked closely with Bombardier to ensure the stock is able to be delivered on time. In most cases the physical units were delivered on time however, the acceptance process has presented significant challenges in the case of the Class 345 and Class 710. 

The trains ordered by TfL from Bombardier are either in operation on, or due to be in operation on, the following lines:

  • S-Stock: Hammersmith and City, Metropolitan, District and Circle.
  • Class 345: TfL Rail and the Elizabeth Line.
  • Class 710: Gospel Oak to Barking, Watford Junction and West Anglia routes.
