    Yes, as in double tracking. From what it looks or seems from what I read Naughton talking about, it seems like there could be a backup of traffic between Galway and Athenry because the passing loop is going to rejoin to an individual track for some of the route, so it is possible a frequent commuter train could result in delays for the city to city services or vice versa. They may have to wait on departure to allow the commuter train to merge and get ahead of them on the individual track out to Athenry or they would have to plan the schedules well so there isn't a slowdown for services coming in on the Athenry to Galway stretch or was I misreading and the passing loop will be a looped out track that spans all the way from Galway to Athenry and stops at Oranmore and Athenry on separate platforms?

    The passing loop is 820 m of second track at Oranmore station, with a second platform, to allow two trains to pass each other in Oranmore station.

    This helps explain a passing loop:

    It will be single track, like now, from Renmore barracks to Oranmore.

    There is a passing loop already on Lough Atalia bridge, beside the barracks.

    Then a new passing loop in Oranmore station.

    Then single trackk as now to Athenry.

    Then the existing passing loop in Athenry, which is where trains can pass now.

    It will happen, when is the question. Should be planning for it now and build up along that corridor. Could we build a NEW town between Oranmore and Athenry?

    IE plan to double the track to Athenry by 2040:

    Galway County Council have already published a masterplan for 1,100 houses at Garraun behind Oranmore railway station.

    The passing loop will reduce delays, and the effects of delays.

    If a train from Dublin is delayed, the train leaving Galway will no longer have to wait for it in the passing loop at Lough Atalia.

    Instead, it can go to Oranmore, and wait there, meaning the pax for Oranmore are not delayed.

    It should reduce it compared to now but isn't the plan to run a more frequent service for commuter transit. So they will have more services along that shorter route but it will also be in contention with the regular city to city service. I would guess, if they time things properly there shouldn't be much delay. Passing trains could get by as the commuter train is at the platform rather than having trains stop on the passing loop to allow a train to continue onto the single track.

    Although you keep referring to them, there is no such thing as a "commuter train" on the Galway line.

    There are trains as follows:

    (1) trains from Galway to Athlone/Tullamore/Dublin - these are typically class 22000 ICRs

    (2) trains to Ennis and Limerick - these are a mix of 22000 ICRs and class 2800 DMUs

    (3) a few trains (not many) that go from Galway out to Athenry, and turn back

    Most, but not all, of these trains stop in Oranmore.

    All of them stop in Athenry.

    Trains pass each other in Athenry, as Athenry has two platforms and two tracks.

    No more diesel trains are on order.

    So the only way to have more services on the section between Galway and Athenry is for:

    (1) more trains to be cascaded from elsewhere in Ireland - I believe this is due to happen in a few years time

    (2) or else if the planned passing loop in Oranmore allows the existing stock of vehicles to provide more services - I am not sure if this is the case

    The politicians keep saying that the passing loop will allow up to 4 tph, but they never state whether IE have the stock to provide this service.

    "I would guess, if they time things properly there shouldn't be much delay. Passing trains could get by as the commuter train is at the platform rather than having trains stop on the passing loop to allow a train to continue onto the single track."

    I don't really understand you here.

    The idea of a passing loop is that two trains travelling in opposite directions will come to a stop in Oranmore (like they do now in Athenry).

    They will both stop, and drop off and collect pax in Oranmore.

    This can't happen now, as the line is single-track.

    You seem to suggest that one train will not stop. Maybe that will happen on some services, I'm not sure.

    Maybe there are some times of the day when the demand from Oranmore is low, and it doesn't make sense to stop.

    What does the reference to "rail buffer" mean in the planning application?

    Signalling, electrification and telecommunication compound (maximum c. 3.4m in height) to accommodate a generator building (c. 20sqm), an electrical building (c. 26sqm) and a fuel storage room (c. 6sqm); 

    Is this a standby generator?

    Or is this generator in use all the time?
