Please elaborate.

not sure what the structure clearance of 1500V DC but definitely that takes a chunk off the roof clearance. Wire clearance depends on whether you use rigid conductor or catenary. At the same time IE are running 9 foot 6 containers. So you're looking at daylighting or otherwise raising the roof height, at least at the Heuston end where the bridge is. Maybe you get away with undercutting away from there but you're still talking serious $ plus the tunnel unavailable during parts of it so no switching equipment between Connolly and Heuston without a trip on the South Wexford, no Westport freight unless you first reinstate the Mullingar-Athlone line. For the return available, better off getting dual mode kit instead.

Irish Rail deserve ZERO credit for opening that route to passengers and any success that will clearly come from its potential being unleashed for Kildare commuters.

Under no circumstances should they be congratulated and applauded for something they were dragged kick and screaming to do for nearly two decades.

They would have walled it up and dynamited it years ago if they could have done so.

Correct. Ultimately the reason for reopening was a FG embracing of a campaign in 2003. I'm no FG supporter, but they ran with it.

It is true that the rail network and infrastructure is a joke, not building a loop in each direction at Clongriffin, despite the fact that it was perfectly possible to do so and the groundwork was already done for it to a large degree just shows you the penny pinching that happens regarding infrastructure in this country.

Although what does take the biscuit is how the main rail line in the heart of this countrys capital city centre is essentially a two line railway with one platform for each direction almost zero redundancy for when something breaks down which leads to delays, fast trains being stuck behind slow trains and all of the crap that creates and the enormous amount of bottlenecks in the system.

However infrastructure are only part of the problem, Irish Rail have a lot to answer for as well with their management of rolling stock and allocation of it, which, lets be nice, is not very good to say it politely.

The problem is two tracks through Connolly, a 10 minute DART or 10 minute Diesel services delivers the same thing through PPT.

Anyway you could purchase dual stock which allow electrical or diesel running but it's not the problem.

To be more accurate level crossings between Lansdowne to Merrion need to be removed or changed to flyovers as well as a triple/quad tracking and redevelopment of the Connolly to howth jct/clongriffin section as well.
Rail infrastructure needs serious redevelopment in Dublin at some point and that includes building the DU as well to spread out capacity better.

The one thing I am wondering about all of this is how it costs 14 million to open this tunnel for passenger use!? Wasn't there already tracks in place inside the tunnel? I know I am obviously uninformed and naive, but 14 million!? Does anyone know what had to be done to get to this sort of figure?

It's really not just about the tracks themselves its about the surrounding terrain and such as well. You have to remember up to now only the occasional train would use the tunnel and your now expanding it to have several dozen multi-ton trains passing through it every day. The vibrations off these things with much more frequent use can destabilise the surrounding terrain and cause collapses or other issues if its not properly reinforced beforehand. Its like anything else if its old you need to invest in it to make it fit for purpose otherwise it could break on you.

I seem to recall the height is a problem and lowering the tracks wouldn't be enough.

Anyway electrification is not necessary

A few questions:

if it ever happens, is the tunnel big enough to take OHLE to allow electrification?

were there ever any stations between the tunnel portal and the junction with the Sligo line?

I'm pretty sure that state enterprises are legally mandated to have everything translated to Irish - so Bus Eireann are in breach of the law in fact.

The embankent of the cutting has been reinforced. Basically it shouldn't result in a landslide during crappy weather. Never did before though, but here we are in 2016.

It did several times, just never usually known as it didn't affect any passenger trains but a few freights did hit landslides over the years.

Reinforcement of the slopes. Drilled holes filled with rebar and grout

Great video. Very encouraging. I think a shorten clip of that video would make for a good advert when opening the line.

Why is the ballast so heavy.

Great

Whats the unused/abandoned bridge over the line, just after you exit the tunnel from the park heading towards Cabra?
Something to do with the barracks?

Yes, the former entrance from the NCR to McKee Barracks.

Wasn't McKee Barracks originally Marlborough Barracks? That bridge being the old entrance from Marlborough Road into the barracks.

Please explain what about this timetable is difficult to read or understand and point to a better example from an operator that you approve of.

Well perhaps I was in my usual, knee-jerk, anti CIE mode in my post, but it was brought on by the suggestion that reading timetables be taught in school. That said, the Dublin/Cork timetable could be improved by removing the token Irish cluttering it up - less is more. Bus Eireann don't see the need to have Irish on their timetables. http://www.buseireann.ie/timetables/1442220927-2.pdf

IE's website is a pain to use especially when it comes to booking a ticket. The company are incapable of providing an all-lines printed timetable for public sale - yet they manage to supply their staff with same. Would it really be that difficult to run off some extra copies for sale? God forbid that they might even make a profit.
