Berneyarms you are absolutely correct - 1713 and 1715 departures wouldn't be the cleverest but 1715 and 1718 might work !

Default Sligo

Had a look at the draft again and a few bits are not adding up on Sligo services, crossing at Carrick on Shannon.

Sligo-Boyle-Carrick 11-12 minutes (departing)
08.55-09.30-09.42 (09.47)
11.00-11.35-11.47 (11.53)
13.00-13.35-13.47 (11.52)
18.30-19.08-19.20 (19.26)

Dublin-Dromod-Carrick 15-16 minutes (departing)-Boyle (should depart)
07.30-09.25-09.40 (09.45)-09.52 (09.57) - 5 minutes missing so arrival into Sligo will be 10.33 at earliest*

09.30-11.32-11.48 (11.51 or 11.52)-11.58 (12.02) - 3 or 4 missing so 12.39 arrival into Sligo*

11.30-13.31-13.46 (13.51)-13.56 (14.01) - 4 or 5 minutes missing so 13.39 arrival into Sligo*

17.05-19.05-19.19 (19.21)-(19.31) (19.34)) - Timetabled right this time however giving the 18.30 up 4 additional minutes tells me they expect the 17.05 to run late so yet again 3 or 4 minutes missing so 20.10 arrival into Sligo*

* Note - 48 minutes for trains getting clear run into Sligo, 53 for train looping just outside Sligo. All above are timetabled for 47 or 48 minutes from Carrick so no dwell time factored in for crossing service.

The 07/09/11.30 in particular will blatantly not run to schedule, some effort with the 17.05 but not worth it as they really expect it to overrun.

When two trains cross at a minimum 2 minutes is required for one service stopping and 3 minutes for another however the norm on Waterford/Galway/Westport is 3-5 depending on which services.

Am I forgetting to factor something here or is it IE making the timetable up, normally we can't stop them adding lots of time on now they are doing the opposite!

Yes you are forgetting something - Carrick-on-Shannon Loop is outside of the station, on the Sligo side, so you would have to allow 1-2 minutes to get to/from it.

That would mean one train just passes straight through with the other train waiting in the loop.

Jamie,

It is a little difficult to know what the timetable planner intends to happen in respect of the Carrick on Shannon crossings, the timings would seem almost to be based on the loop being in the station rather than just north of it. There appears to be no merit in adding time to northbound trains between Dromod and Carrick as this is likely to lead to the northbound train sitting waiting for time on the platform while the southbound train waits outside.

I don't think it will affect the ability to run the timetable as published other than that northbound trains may drop 2 to 3 minutes reaching Boyle. The allowance from Boyle to Ballymote is well padded so I would expect any time lost to have been recovered by then.

You are right though, it is not quite as it should be.

Ah I see, whats with that set up, looking at maps there is a second platform and room to extend and for a passing loop.

It avoids having to install a disabled-friendly footbridge with lifts, and platform extension in one side.

Cost reduction basically!!

It's exactly the same at Wexford.

How do we ever cope in Athy, Carlow, Muine Bheag.......

I think the second platform would fit a 4 coach on it or just about, there would never be anything bigger crossing there.

It's a poor excuse, I hope there is a better reason.

Well given the costs involved of installing a bridge with lifts, and the fact that (at the time) virtually no trains crossed there, it's not that surprising.

It's a perfectly valid reason - it's not going to cause that much hassle and it saves cash.

I get the impression the loop isn't at the station so as to allow the platform to be straighter - hence a smaller gap between train and platform.

Default Athy access

As well as the ramp to platform 1 (station building side) in Athy there's a gate at platform 2 (platform 2 is the side opposite station building) with a ramp leading out to the street. Think it's always locked though.

This is not reflected in the information on the website and is just one of a considerable list of inaccurate pieces of information for various stations around the country.

Platform Access

Via ramp to platform No.1
Footbridge only to platform No.2

Correct, would attract a lot of free loaders if opened.

Simply thing that happens is whichever train has a wheelchair passenger on board and crossing with another is cleared for the main platform. If the rare case of two wheelchairs in my experience train arrives and departs before switching lines and containing its journey.

Perhaps however the gap wouldn't be that big and there are a lot bigger gaps on the network. Anyone know what year it was moved out?

IE could still been more creative with the Sligo schedule than they have been.
