Class 755
The Class 755 is a modern bi-mode multiple unit (BMU) manufactured by Stadler between 2018 and 2020. It is a part of their FLIRT ("Fast Light Intercity and Regional Trains") family of trains, and accompanies the Class 745 on the network. These trains are now operated by Greater Anglia on their regional routes, such as the Gainsborough line (Marks Tey to Sudbury), Wherry lines (Norwich to Great Yarmouth, Lowestoft), and East Suffolk line (Ipswich to Lowestoft).
There are two subclasses, the 755/3 and 755/4. The only difference between these subclasses is length and, by extension, seated capacity. The BMUs entered revenue earning service on 29 July 2019. They replaced the Class 37 and Mk 2 carriage formations, Class 153, Class 156, and Class 170, and so were responsible for the much of the loss of variety of rolling stock on the Greater Anglia network.

Subclasses
There are two subclasses of the Class 745. The 755/3 is formed of 3 passenger cars per unit, alongside the power pack, whereas the 755/4 is formed of 4 passenger cars per unit, also alongside the power pack. Both subclasses can theoretically be found across all of Greater Anglia's regional routes, but the 745/3 is prioritised, as expected, for operation on lesser used routes, such as the Gainsborough line (Marks Tey to Sudbury).
Across both subclasses, there is no difference to the on-board experience. Both subclasses are just as accessible with each other. Even though the 755/4 is longer, there is still only one toilet across the whole train. So, the difference between these subclasses lies solely in length and capacity.

Footnotes
- Bi-mode multiple units (BMU) can operate with a pickup along appropriate track (i.e., where there are overhead lines or third rail installed), and otherwise using a diesel engine to generate electricity, for added flexibility.
- A pickup is a piece of equipment installed on a train to connect it to the supply of electricity, usually in the form of overhead lines or a third rail. On the Class 755, it will be used during electric, as opposed to diesel, operation.
- The formations given do not include the power pack vehicle. The power pack vehicle contains the engines and generators required for diesel operation. It contains a narrow corridor, so it is still possible to walk to and from each end of the train.
