Question to the Department for Transport:

To ask His Majesty's Government what plans they have, if any, to introduce double decker trains to the UK rail network.

The Government does not have any plans to introduce double decker trains to the UK national rail network.

Double decker trains would require significant civil engineering investment including modifications to station roofs, electrification equipment, signal gantries, bridges, platforms and many other structures close to the line which would be costly and disruptive to passengers.
