Question to the Department for Transport:

To ask the Secretary of State for Transport, what adjustments were required to the IEP contract with Agility Trains to install filters on the Class 800 trains for use on the East Coast mainline; and what the cost was of those installations.

The Intercity Express Programme (IEP) contracts require Agility Trains to provide trains that are compatible with the network. There are mechanisms within the contractual structure to allow for adjustments to be made as a result of required train modifications such as the installation of filters on the East Coast IEP fleet. Discussions are currently ongoing between DfT and Agility Trains on the implementation of the required contractual changes.
