Class 220 testing and operations
During 2001 and 2002 the class 220 Voyagers underwent test and commissioning running on the Monk Bretton branch near Wakefield and on the East Coast Main Line (ECML).
The class 220 units were built by Bombardier at their Horbury (Wakefield) and Bruges (Belgium) plants and consisted of 4 cars each having an underslung 750HP Cummins QSK19 engine with alternator and two longitudinally mounted traction motors driving one axle on each bogie via final drives and cardan shafts. The units also featured rheostatic and friction braking.
The class 220 units are known as Voyagers and are non-tilting but have the same tapered body profile as the tilting class 221 Super Voyagers .
Serco staff were involved with all the initial test running under a specially written Class 220 Railway Safety Case on the Monk Bretton branch and the ECML. The units were delivered by rail from Horbury to Crofton Depot which used to be a track assembly depot. Bombardier spent a lot of money upgrading the facility with two portable train sheds and pit roads, Portakabins etc.
The depot is still in use today servicing Class 170's and 222's as well as Voyagers and latterly the class 180's. Horbury Works has now closed.
Serco undertook all the formal Acceptance Testing and a multitude of train operations on the class 220 fleet including commissioning runs on every unit.
Here are a selection of photos of the class 220 units in action and some of Horbury Works and the Crofton facility.

Crofton Depot & Horbury Works
Crofton depot is now used as a servicing and stabling point by CrossCountry Trains. Horbury Works is now closed.

Monk Bretton testing
Monk Bretton was just around the corner from Crofton - Oakenshaw signal box controlled access to and from the line although it has now closed. The line was only used by a sand train which travelled to Redfearn's glass works at the end of the line once or twice a week. The line was originally part of the route between Leeds and Derby and was laid in part with CWR on concrete sleepers - although it had a 40 mile/h limit when we were there.
Although it had no signals (except the protecting exit signal for Oakenshaw) the line was fitted with Tilt And Speed Supervision (TASS) balises for test purposes.

In addition to the slow speed running on the branch the trains also ran between York and Darlington where they were put through their paces. This was the same route where the prototype HST was tested 30 years before.

|In April 2008
undertaken utilising a class 220 to assess new brake pad material for both
the 220's and 221's. The pads had already been
proven on the dynamometer rigs at the manufacturers and the on-track testing
was to validate their performance in traffic.
The trains were once again based at Crofton Depot, Wakefield which was very convenient for the ECML.
|I was back at Crofton after an absence of over 5 years, where 220002 awaits a test run to Darlington on 23rd April 2008 in connection with tests on new brake pads.|
