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.
Further testing included bridge resonance tests -
Underbridge resonance is a phenomenon that occurs
when the frequency of loading from rail vehicles matches the natural frequency
of a structure or particular elements of a structure - namely a rail
underbridge. Incidents of ballast moving on underbridges when being traversed
by TGVs on SNCF lead Railtrack to instigate a test series on several new built
DMU's (including class 180 and class 221) although realistically the design of
underbridges in UK was different from SNCF and the fact that TGV's were
articulated seemed to have passed Railtrack by.
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.
Future use of the units
Unfortunately most of the units have been dispensed with by FGW - a short sighted policy I think as they knock the Voyagers into a cocked hat. Until recently t 3 were operating with Northern Rail (not much 125 mile/h running on the route between Manchester and Blackpool methinks!), First Group with Hull Trains' services and Grand Central have a couple each too. The first GC example 180112 was delivered to Heaton depot on 25th July in a distinctive livery of black with orange bodyside stripe, and named 'James Herriot'
In July 2011 one was spotted at OOC and in November FGW will soon take the three back from Northern Rail plus two from storage giving them 180102, 103, 104, 106 and 108 in time for the December timetable changes. Let's hope they soon re-paint them from the hideous Northern livery into the not quite so hideous FGW livery.

|In the early summer of 2000 the unit awaits a path from Old Dalby to Old Oak Common. It was parked out of the way at the former Asfordby mine complex due to the impending upgrade of the test track on behalf of Alstom.|
|On 21st December 2000 in the middle road at South Ruislip on the former GW/GC Joint Line, the unit awaits a return path to Old Oak Common during its early shakedown runs. Note the horn grilles on the cab roof - a rare picture of them in place.|
|The inside of the unit was Spartan to say the least|

|On a splendid January day in 2001, 180101 sits inside the yard at Southall having just arrived from Reading on a driver training run|
|By February the unit was under test and is pictured in Stoke Gifford yard next to Bristol Parkway station ready for a run back to Swindon|
|The testing was undertaken by Alstom staff - here are the men at work (and a visitor)|
|At the heart of the GWR! 180101 pauses at platform 3 at Swindon en route for Bristol Parkway in April 2001 Note the horn grilles on the cab roof are now removed due to them vibrating at speed.|
|And in the London terminus of the old GWR - platform 1 at Paddington|

|In May 2001 the unit is captured on the Up road passing the 100MP - at the former Badminton station|
|On a rainy day at Swindon 180102 is pictured from the cab of 180101 during joint testing.|
|50 miles from Paddington 180102 approaches 180101 at speed near Didcot|
|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..
......and in service

|180107 pictured about to leave Exeter with a service for Paddington on 3rd October 2005|
|180109 departs from Westbury on 19th October 2006 - note that it by this date they were running without the coupler covers|
|180110 at Reading on 19th October 2006|
and new operators

|180111 in its new role with Hull Trains passes Newark at speed heading for London on 2nd July 2008. The livery is still based on First Group's hideous colours of pink and purple but with a name change. Shame they didn't keep the Hull Trains original livery.|
|180110 at KX with the 16.05 to Hull on 19th June 2009|
|180113 at KX with the 16.05 to Hull on 14th August 2009|
