Testing Alstom's Class 180 DMU

After several weeks of trials at the Old Dalby test track the first class 180 unit was delivered to First Great Western's Old Oak Common Depot, west London during July 2000.

Known as the Adelante's, the first of fourteen 125 mile/h units was built by Alstom (formerly Metro Cammell) at their Washwood Heath, Birmingham works and consisted of 5 cars, each with an underslung 750HP Cummins engine with Voith hydraulic gearbox and final drives. The gearbox also incorporated an hydraulic retarder to assist with braking.

The trials commenced in May 2000 at the Old Dalby test track when the first unit 180101 was delivered by road to the test track. This was because the operational Railway Safety Case to enable Serco Railtest to run the train under test conditions was not yet accepted and therefore the unit could not run under its own power on Railtrack.

After the completion of preliminary testing at the test track the unit was loco-hauled to Old Oak Common depot but, due to further delays in obtaining the Testing Safety Case, running did not commence until December 2000. It continued into the summer of 2001 mainly on the GW main line between OOC and Bristol Parkway via the Badminton route.

Serco Railtest also undertook to operate the train for the public launch of the Adelante unit at Paddington although as it turned out the launch was rather premature as the introduction of the units was severely delayed due to numerous problems.

We stayed near Great Portland Street tube station at the Forte Posthouse which was very convenient for the city's attractions, food and drink etc. Having numerous 24 hr convenience stores in the locality was also very useful for picking up sandwiches etc for the night shifts we often undertook. We used to drive to and from OOC along the A40 - we were leaving Town when everybody else was arriving and vice versa - so no real traffic problems except Friday afternoons trying to get home.

Thanks to the combined initial efforts of the Serco and Alstom teams all the class 180's eventually entered service on the GW main line.

Unfortunately it would now appear that the units are no longer required by FGW - a short sighted policy I think as they knock the Voyagers into a cocked hat.

 Here are a selection of photos of the class 180 units in action.

180 launch SPM After the testing came the public launch at St Philips Marsh depot in Bristol. The launch also revealed the First Group livery as applied to the HST's. Note the mythical number on the HST power car 43001 - it doesn't exist anymore being originally allocated to one of the prototype HST power cars - the other being 43000..
