At least the levy for the Green Line extension (to Cherrywood) was actually eventually spent to build the extension.

I wonder is the cash collected for other projects on a very long finger (Metro West for example) being protected?

Im not entirely sure that Cherrywood got the money from the developers.

Tom Manning...RPA.

However, Tom Manning of the Railway Procurement Agency said the property developers' difficulties had not affected the line's development.

"There is a 30-year timeframe for the State to recoup the money, so that could be as many as three or more economic cycles," he said.

From 2012 in relation the the Cherrywood luas.

An estimated €150 million of the €300 million cost of the Luas Cherrywood extension was to be funded by development levies but much of this has yet to be paid for reasons generally associated with the downturn.

MW has one for sure.

Yep with Fingal and South Dublin. Given that DU is far more likely to go ahead than MW, I'm surprised the city council didn't draw up a development contribution scheme for it.

I assume that means that whatever was collected went towards the extension??

All very opaque, isn't it?

Possible plans to extend Dart further north as part of DU project

This isn't news, it's been planned for years. I recall news stories and drawings within a year or two of Transport 21's announcement of the possibility of going as far as Drogheda.

Looking beyond DU - could we see the underused Phoenix Park Tunnel alignment becoming a possible future Luas line once Dart Underground is built?

As part of what route? Doesn't seem to be any obvious one suited to light rail.

Doubt it, it is still in active daily use.

Is the tunnel single track?

Well given that every single disused alignment into the city is currently Luas (Green Line) or about to be (BXD), I'm sure that they'll come up with some way of getting better utility from this section. Doesn't one of the crayon plans for Fingal include a service from Heuston northwards?

There is plenty of space on that alignment, they could reduce IR from two tracks down to one and potentially have plenty of space leftover for Luas.

Should be possible to gauntlet the two gauges through if needed

Sam Russell

In my view, it was one of the daftest decisions that the Luas project made was to go with the UK gauge rather than the Irish one.

A similar mistake is going to be made with the BRT design if they go with bendy buses.

Ancient mythology is that it was done on purpose to stop Irish Rail getting their hands on it. It has reduced rolling stock costs too but had definitely cost in flexibility.

With Harcourt St. Station mostly empty since Pod closed we could have been looking at a proper reopening of the Harcourt line if it was 1600mm.

I don't believe that ancient mythology had anything to do with the guage. First of all, it was CIE that started the project in the first place through their Light rail office back in the mid 90s. The were removed from the project when the RPA was created in 2001 through an ammendment of the Transport Act. The guage is the international standard and was always going to be. There is absolutely no evidence to suggest the luas guage was ever going to be 1600mm and nor should it have ever been.

As for Harcourt St Station, it was never a runner to reopen and would not have provided a better service than the current luas line.

Even in post DU world, I think the PPT route should be retained as a heavy rail alignment.

Daft question and probably done to death but was there much advantage or saving in going for the slightly narrower gauge ?

Sam Russell

Even the old Victorian trams were the 1.6m gauge. It made no sense and probably saved very little - given the saving only applied to the rolling stock. It is the same rail, only slightly further apart.

Think of the benefit to tourism if we had a few geriatric trams running from Amien St (Connolly) to Kings Bridge (Heuston)? Other countries do this. London still run a few RouteMaster buses on heritage routes.

I think the problem with that idea is more to do with lack of enterprise, than gauge.

Probably made it easier to get "off the shelf" (i.e. less customised) trams from Europe.

Again, it only saved on the trams themselves, not any of the infrastructure.

Sam Russell

Could DU be built using a single bore tunnel something like those used for the Dublin Port Tunnel? It should be a lot cheaper, and a lot of the London Underground uses this type of tunnel.

afatbollix

Only the older tunnels are single bore. The standard is twin bore now for safety.

Trams were part of the "infrastructure". What is your point regarding building luas to a 1600mm gauge?

murphaph

Standard gauge for Luas was absolutely the right decision. Being able to buy off the shelf makes a huge difference to your bargaining power.

The question should be the other way round - what advantage would there have been in building to the less-common Irish standard? You can't mix trains and trams on the same line (for safety) so none of the existing rail stock could use it anyway. If you ever wanted to convert it to train operation, you'd need to change the power and signalling which would be expensive. And, even then, no-one in their right mind (except Los Angeles in the 90s) would run heavy rail on-street.

So, given that we're never going to run Irish trains on it, why build it to an Irish train standard?

And would they only be single decker trams (were there single decker trams) or would we all raising the cabling height too? Would we be happy delaying the actual trams behind the heritage trams for sake of a few tourist?

Sam Russell

I for one would not travel on the open top deck sitting a short distance from the overhead power line. Maybe we could make some look-a-like old trams - the way 'old vintage' wedding cars are done (based on Ford Granada parts).

Maybe I mean trams that look old but are not.

We'd better give this a bump, because this thread is about to fall off the front page of the forum.

Let's try this:

I see SF are having their conference this weekend. Where are they on the interconnector project?
