Class 150/2
After the success of the class 150/1 DMU, 85 class 150/2s with corridors were ordered. These units had the crew doors on the sides powered, like the prototype, meaning these units had door interlook where you cannot release the brakes when the doors are open. Like the other 150s, they were fitted with BSI type couplers and were geared the same. Numbering for the units are as follows: The set numbers range from 150201-150285. They are made up of a 57XXX car, and a 52XXX car, these were numbered as 57201 - 57285, and 52201 - 52285. The 52XXX cars were fitted with lavatories meaning each set had one lavatory. These units are still in strong use today, they are leased by the following TOCs: Northern Rail, Arriva Trains Wales, and First Great Western.
