Only the Bs have Jacobs bogies - under the centre articulation joint.
The C and D class trams have fixed trucks (or bogies if you use the
European terminology) which don't rotate freely under the carbody.
The E class have normal bogies which rotate around kingpins - one at
each end and two under the centre section.
Three of those bogies are powered.
