    Notice that the generator in the DVT on the Mark 4's is being shut down at nights. Assuming to save fuel, its being long overdue and should of being happening years ago.

    Are they easy to start as they would of being the reasons they were not shut down before so have IE developed some way to start them quickly. Not sure if its happening in Cork but it has being in Dublin. All the sets that I have saw shut down have being without the 201's attached.

    Is it only a matter of time before the 201's are shut down at nights and started again for service in the mornings.

    They're modern generators, I wouldn't imagine they're particularly hard to start at all.

    I'm sorry... WHAT? They were running as is? Good grief. No wonder IE reduced the number rostered "to save money".

    When VIA Rail refitted their EMD 645 powered F40PH a start/stop system was added, and they have much colder weather to deal with.

    Yep they used to be running 24/7 like the old Mark3's. Would love to see the costs involved!

    Why would they leave them running all night?! Seems daft.

    Who knows, operational convenience? but its IE here and this wouldn't be the first daft thing to be done!

    I could understand it maybe in exceptionally cold weather like that absolutely freak winter a few years ago, but otherwise it wouldn't make much sense.

    They should have sockets on the platforms / sidings for power when the train is parked for long stays too. It should be possible to connect a major 400V three phase supply to the power car or The DMU sets for the 22000s to provide heat and light for cleaning and storage without having to burn diesel.

    Cheaper and more eco friendly to use mains power possible.

    Shouldn't be very complicated as Irish trains use normal mains voltages and frequencies for everything on board. Its similar to hooking up a portacabin etc

    I wonder what the bill is for running the engine block heaters on those things.

    They don't even need a mains connection, the trains are cleaned more less after the last service while the 22's cut power and fuel burn 20 minutes after being stopped and automatically shut down engines. Walk in Heuston station after a 9 at night and any 22 that's not operating a service will have none or a max of 1 engine running and it's almost silent while they are being cleaned. The fuel being wasted would probably be less than a mains cost.

    They have even put the doors on the 22's on timers to close as it's supposed to save fuel. Now I can't see how it does.

    Heating I'd imagine.

    Probably a variant of this system:

    Probably adds to the cost of maintenance of the doors, my experience at Docklands with 22ks is that the door closes to the platform ends up closing and opening multiple times before departure as people arrive to the train.
