Class 175 Coradia units
|Fitted with Cummins N14 450hp/335kW engines and Voith transmission,
these two and three x 23m car long units were built by Alstom (formerly Metro Cammell) at
their Washwood Heath, Birmingham works in 1999 and allocated to the then new
Capable of 100 mile/h with Westinghouse 'Westcode' brakes they had BSI couplers and weighed in at approx. 36 tonnes each vehicle.
The units' early running and commissioning was carried out at the Severn Valley Railway where a special temporary shed with a pit road was built for the purpose outside the old goods shed at Kidderminster. Following low speed running the first few 2 car units came to the Old Dalby test track where driver training up to 90 mile/h was undertaken, mainly confined to the Chester traction inspectors and trainers.
The author spent some time at Old Dalby when the units were being commissioned as well as arranging the Safety Case for test operation by Serco Railtest on behalf of Alstom Transport. A number of tests were run from the SVR at Kidderminster, including performance tests up the Lickey Incline among other destinations. Later operations involved delivery of the units to Chester depot and numerous test runs from there.
Comparison tests with class 465 units were also undertaken on the Southern Region.
The 175's were amongst the few classes which retained their original livery for a considerable time but I'm afraid they have now succumbed to fashion!
