Today's Cancelled Trains
UK: The prototype Independently Powered Electric Multiple-Unit has entered trial passenger service on the Manningtree –Harwich branch, where it is scheduled to operate on weekdays between January 12 and February 13.
The IPEMU comprises a Bombardier Electrostar Class 379 four-car 25 kV 50 Hz EMU which has been retrofitted with Valence Technology lithium iron magnesium phosphate batteries for off-wire use. It will be used to assess the potential for battery-powered trains to be used on non-electrified routes between electrified lines, or on branch lines which would be expensive to electrify. The data gathered will help to determine whether any future IPEMU should be a straight battery unit or an overhead-battery hybrid.BATTERY: StartPac’s Li64RR lithium ion 64 V battery for use on locomotives is a 150 kg unit based on aviation industry technology. It is designed to replace two 32 V lead acid batteries weighing 1000 kg.
‘The Li64RR is based on the newest technology, and is extremely safe, lightweight and durable’, according to StartPac engineer Mark Marar. ‘It ushers in a new era for locomotive batteries, with the cumbersome and bulky lead acid batteries becoming a thing of the past. Train owners and operators will benefit enormously from using a battery that needs minimal maintenance and can be manoeuvred more safely and easily.’
