Question to the Department for Transport:

To ask Her Majesty's Government what recent assessment they have made, or plan to make, of Class 150 diesel multiple units in relation to their suitability for modern rail travel, taking into consideration (1) speed, (2) acceleration, (3) reliability, (4) emissions, and (5) convenience, comfort and noise for passengers; what kind of services and distances travelled such units are now suitable for; and what is their estimate of the useful future life of such units.

There has been no assessment of the suitability of Class 150s. This will be a decision for the operators of Class 150s taking into account the needs of their passengers.
