Description

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.

Speaker(s)
