Adrian Stevenson (Siemens) and Alan Thwaites (LM Trains) will describe the challenges faced in increasing the operating speed of the class 350 Desiros from 100 to 110 mile/h
(160 to 177 km/h) The existing squirrel cage rotor short-circuit rings within the traction motors could not cope with the extra forces at higher rpm, and on EMUs with worn wheels the combined effect could be an additional 1 000 rev/min.
Lateral dampers on the bogies were changed along with the aerodynamic properties of the BR Brecknell Willis pantographs. Braking performance under full load conditions was tested using collapsible water-filled containers originally designed to represent passengers when testing lifeboats!
The higher top speed has enabled London Midland to cut up to 35 min from Crewe - London timings, and to run two services in what was previously a single 100 mile/h  (160 km/h) train path.


Adrian joined BR as an apprentice at Ramsgate and is now Technical Manager for Siemens. Alan joined BR as an engineering graduate and is now Timetable Development Manager for London Midland Trains
