Test­ing process

Rail (UK) - - News -

When the trains ar­rive at Edge Hill by road, they are un­loaded and im­me­di­ately cou­pled.

The trains are then moved into the main shed, where com­mis­sion­ing takes five days. CAF car­ries out this work, which in­volves test­ing equip­ment in­clud­ing me­chan­i­cal cou­plings, air pipes and elec­tri­cal fit­tings. Each in­di­vid­ual sys­tem is also fired up be­fore more test­ing be­gins (in­clud­ing on the brakes)

North­ern Project Man­ager Garry Bar­tie said that type test­ing will be needed for six trains (three Class 195s and three ‘331s’). This in­cludes load weight tests on the main line at speeds up to 100mph.

Cur­rently they are run­ning be­tween Edge Hill, War­ring­ton and Carlisle. North­ern is crew­ing these with Rail Op­er­a­tions Group pro­vid­ing sup­port and res­cue lo­co­mo­tives. So far there have been no fail­ures.

Cus­tomer-spec­i­fied tests are also re­quired, and then fault-free run­ning be­gins.

Bar­tie told RAIL that the first three trains of each fleet (‘195’ and ‘331’) must com­plete 1,500 miles each, with the re­main­ing 92 trains all re­quired to com­plete 500 miles run­ning. If the trains fail then the clock is re­set and they must start again. Bar­tie said 500 miles is roughly the length of the planned ini­tial ros­tered du­ties.
