This article from the Railway magazine shows Lab 4 being tilted
The article Below was supplied to us by Kit Speckman who worked on the APT project and was effectionalty known as Mr Tilt
Unit 1032
TRB 60750
The only survivor from 1032 is the former buffet 60750 or better known these days as Lab4.
It was converted into an experimental tilting vehicle for the APT project and became the first vehicle in the world to tilt at speed with people on board.
It's seen here after preservation at St Leonard's.
I was later sold onwards to a small group at the Pump Museum in Walthamstow but has since been purchased by the APT support group who initially moved it to the Electric Railway Museum in Coventry and when the museum was forced to close the group moved it to the Battlefield Line
