The Class 320 is effectively a 3-car derivative of the Class 321 units found in and around London and the Midlands. Built in 1990[1] by BREL in York, 22 3-car sets were ordered by SPT to supersede the aging Class 303 and Class 311 stock which were by then 30 years old. The units run on 25 kV AC overhead line supply via a Brecknell Willis High Speed pantograph, then routed to the transformer and then finally onto the four Brush TM2141B traction motors. With much shorter passenger journeys in mind, the Class 320 units lack the toilets of the Class 321 units and also have a lower speed capability (75 mph) due to the much closer spacing of stations on the North Clyde route, and also that they are not fitted with yaw dampers. 320301 has now been fitted with yaw dampers during July 2010, and once the whole fleet have these fitted the Class 320 will be allowed to travel at 90 mph. One distinctive feature is the interior decor, which includes paintings of various landmarks and famous sights along the various SPT rail routes on the car ends. You can get these on the Cathcart circle line in real life so I think we should have this in TSW 2.
Aye, it would add some much needed loco diversity for the route. Just to let u know that SR are drawing up plans to replace them
