Signalling on Maynooth line

No that's exactly my point. The existing dart line runs straight through some of the busiest roads on the south side of Dublin. That works for a higher capacity then the maynooth line so plenty of room to grow capacity without closing the LCs. And do you really think Irish rail would get away with putting ugly bridges or tunnels through the leafy suburbs of landsdown road, sandymount, Sydney parade? Yeah sure. Those residents wouldnt tolerate that and neither will the coolmine residents.

You can believe in your head what you want to about the ability to run extra services retaining the level crossings, but I'm telling you that you are wrong.

Ultimately in the long run the crossings in southeast Dublin will also have to be dealt with as well.

Correct me if I am wrong but many of the crossings on Maynooth line are manually operated, this adds a further time delay and the higher the line speed the earlier the crossings will be closed to ensure the train gets a clear run and not a danger signal and have to slow down.

In general across the network LCs will be closes at least 1.5 minutes before a train passes and longer if some are very close together.

Rellys crossing is manual but will be closed soon as theyre building an overpass to replace it.
Ashtown looks like its being changed to automated setup with barriers as they recently put up 3 light poles at the station with the foundation for the 4th there too.
Coolmine is an automated LC.
Clonsilla is manual but the LC down the maynooth spur is automated.

Those are the ones i can recall.

You forgot Porterstown - automatic barriers.

Maynooth line
2nd July trains from Clonsilla to Coolmine (via Coolmine crossing)
08:02
08:12 (+10mins)
08:25 (+13mins)
08:35 (+10mins)
08:47 (+12mins)
08:56 (+9mins)
09:17 (+11mins)
average period between trains - 11mins

That suggested bridge which you speak of would eliminate a lot of traffic delays around your locality in that one hour.

Four of the five crossings in Dublin 4 are in residential areas with very little space to allow for bridges either over or under the line. At the very least, pricy CPOs and lengthy line closures will be needed for any bridges.

In the case of Merrion Gates, there have been numerous proposals for a ring road running along the seafront for many years now. This, more than anything, has held up plans to bridge the railway here.

So whats wrong with local people opposing of an unnecessary development that will greatly impact the ammenities for local children and greatly impact residents access to their local shopping center? If this was an existing road then it could be a different story as people bought their property knowing that they were living on a busy road. But to put a busy road through an existing residential area is ridiculous. Especially when the closing of the LCs on other busy routes (e.g. merrion gates) is not even being considered.

So, you're a NIMBY who is more concerned with how long it takes *you* to get to the shops over the greater good. And who's misinformed about Irish Rail's overall plans. Solid argument against the works there...

On a slightly different note, will the Maynooth commuter service ever be extended to Enfield?

Unlikely, as it'd require double tracking which is not cheap.

They should put a toll on all the level crossings :cool:

Imagine the tailgating it would produce

On the bold, it would be very naive to think that

1. The shopping centre is oriented solely/primarily towards the locals of Dublin 15 (it is right beside the N3, after all), unless you are referring to somewhere like Roselawn?

Argue the routing, perhaps, but the benefits of removing the interaction between trains and road are abundantly clear, especially if the traffic on the line is to increase.

bovis is probably talking about Roselawn shopping center (sic).

Argue the routing - that is exactly the issue that bovis has - moving the traffic from a busy road to very quiet roads. If the proposed bridge was over the Coolmine LC there would not be a problem.

This thread (inevitably) drifted off my original question but it was good to get an answer to that question and correct my misconception that there were LCs on the northern line.

Worth noting that closed gates mean idling vehicles which mean emissions on the approach roads. That the railway line was built along the waterway for historical reasons means not a lot of flexibility there in terms of how to locate the bridge ends. Eventually the aim is electrification of Maynooth which will lift property value and reduce train emissions - quicker, more frequent trains now builds the business case for that.

In terms of the bridge through the estates, clearly traffic management will be important there assuming ABP don't decide IE must go a different way but the no build alternative is morons crashing the gates or bringing down overhead (Merrion Gates). Yes, level crossings exist even on quite high speed lines but it increases risk massively and given the litigation culture of the late 1900s/early 2000s this means cheap and cheerful won't do anymore.

'The safest level crossing is a closed one' - I was taught that many moons ago when I joined British Rail. It is still valid
