Luas Cross City (Line BX/D) [now open]

cgcsb

I wonder how quickly metro will fill up and suffer from capacity issues. Given how quickly it happened for luas, about a decade, including a global financial crisis. It won't be long before there's talk of providing relief by extending DART to the airport, building DARTu to provide more cross-liffey capacity and whatnot.

I'm still in the camp that thinks it will never happen for political reasons. The politicians are scared of it, I predict delay and cancellation. Future re-design, rinse and repeat.

It's getting to the stage now where that option is getting less and less attractive. The city is choked, there's increasing urbanisation, a shortage of serviced housing, longer and longer commutes, the M50 cannot be widened any further, there are no low hanging fruit Luas lines that they can build instead etc.

They've backed themselves into the corner of it becoming no longer feasible to drop projects like these. The fudge options have been exhausted.

They are now talking about widening the M11 at Bray "in an effort to ease congestion" in the morning and Evening.

FFS, I really worry about the lack of foresight of some of the idiots in charge.

It’s capacity is enormous they can run every 90 seconds if they go driverless, I’d imagine it will start at 3/4 minutes at busy periods so can effectively double just by adding rolling stock. There is also talk of starting with shorter trains that can also be lengthened as the platforms are to be done at 90 mts which also adds a lot of capacity space.

Quick google and some maths tells me that Crossrail will have a capacity of 36,000 pph.

I'm fairly certain we'd need less that half of that for this side of the century, and metrolink is due to be around 24,000 pph (can someone confirm?)

Muahahaha

It's quite astonishing when you think that Metrolink station at Tara Street will mean that the Irish Times office will be literally at the major intersection of Metrolink and the heavy rail network. It will have the best public transport connections in the country!

haha that reminds me about 6 or 7 years back I was walking along on Townsend St outside the Irish Times building and up the ramp of the underground car park came editor Geraldine Kennedy in a flashy black Merc. She hit the brakes, looked at me with one eye and waved me along. Somehow I doubt the IT journalists will ever be using a new Metro interchange while they have a nice handy car park right beneath their offices!

Uncanny - the precise same thing happened to me too!

In fairness, Fintan O'Toole cannot drive a car.

Most people can't, but they don't let that stop them.

Widening a national road to reduce commuter congestion, a self defeating exercise. The entire transport profession across the world regards this as laughable.

Running 60mtr trains at 3/4 minutes? we're already beyond that. The green line has 55m trams doing the same frequency and it's not possible to board some trams at most stops in the rush hour. 2027 is 9 long years away.

A high floor metro with no driver has a good bit more space than a luas, no wheel arches, no driver cabs and the metro is wider.

And less seats and more standing room gives even more capacity. More frequency also increases capacity.

I think there's also a younger generation of politicans in power who I'd guess have travelled through foreign cities in their college years as opposed to the political generation on the way out that has only seen foreign cities from the back of a limo.

Not building the metro is getting close to the stage of political suicide.

They'll have nothing to worry about, they'll be drawing their pensions by the time their inaction is really noticed.

Oh I’m not so sure about that to be honest. I think with our economy not breaking even at the moment due to massive overspend on maintanence (day to day spending not capital) with brexit, and local political opposition etc I can see metrolink going the same way as metro north.
I really hope I’m wrong by the way.

Inaction is only political suicide for them if we make it so.

I use the m50 most days, it appears to me that they could have fit another lane in, and it could be done relatively simply now... basically continue the auxiliary on as the mainline and there is enough space to do this between the bridge support structures between most junctions, why they didnt do this the first time round seems madness to me, the extra cost would have been minimal in the scheme of things, given that you were going to get an extra bloody lane!

Do you mean a lane that would come and go between bridges? That would be a terrible idea, the resultant merging before each bridge and exit would murder the capacity of the entire motorway.

If the 'extra lane' that reappears between bridges is the hard lane, it would not be such a problem. They do this on the M25 around London.
