A Class 755 Train PowerPack Car
The picture shows the PowerPack car of a Class 755 train.
Note.
- The two covers to give access to the two engines on each side of the car.
- The shared Jacobs bogies between the cars.
- The pairs of shock absorbers between cars.
The Jacobs bogies and the shock absorbers are probably used to help give the trains a smooth ride. The Wikipedia entry for Jacobs bogies says this.
Instead of being underneath a piece of rolling stock, Jacobs bogies are placed between two carbody sections. The weight of each car is spread between the Jacobs bogie. This arrangement provides the smooth ride of bogie carriages without the additional weight and drag.
After my half-dozen or so rides in Class 745 and Class 755 trains, I wouldn’t be averse to seeing a lot more of these trains in the UK.
