That's a bit ridiculous, Ireland adopted the metric system a long time ago now. You would hope that all public transport services would do all their of their measures in metric.

Why?

All the lines have mileposts every 1/4 of a mile. They would all have to be changed at a substantial cost.

If it ain't broke, why fix it.

Somewhat off topic anyway.

Del.Monte · 28-11-2016 07:50PM

It always amazes me that CIE haven't changed the mileposts as they love squandering money, but I'm sure that they will get to it sooner or later with all the money they will save by the impending closures.

no no, that money is to spend on more rolling stock to park up in the inchicore scrap yard.

I agree, totally off topic... just jarring to see MPH as an official measurement in Ireland. I know you hear the odd person say miles per hour and refer to the price of something in pounds but in general it's metric all the way. No real need to get into a Metric v Imperial discussion here but I would imagine government policy would be that all units of measurement should be done by metric for consistency across the board.

I was amazed a few years ago to discover our plumbing is still in imperial units. Pipework is in inches so half inch pipe not 15mm. The UK has been metric for decades. That is why I was told plumbers tell you not to buy, and say they will not fit, plumbing supplies from B&Q. [The olives do not fit and will not work].

Strange but true.

The DART is fully metric, speedo in the cab is in KPH and the datum markers on the OHLE are metric. The rest is imperial, which matches with Northern Ireland which helps. Will it make the trains run on time, nope so isn't worth discussing

Part of the issue here is the signalling has a gap between the Mainline and Suburban systems, both have very limited visibility of whats happening on the other side so sequencing trains can be a problem, Suburban can see trains all the way to Belfast, but has almost nothing on whats coming through the tunnel

All the drivers are Heuston, so aren't hugely familiar with the route and the complex routing around Connolly so things were a little cautious to start out with, driver training still ongoing

the " odd " person

ask anyone over 30 , how far the nearest town is and count the answers in Kph,

seriously

Suburban can't see all the way to Belfast (technically there's also no longer suburban by the way but still generally regarded as such), the limits they can see are an overlap with other signallers, the overlaps being just beyond Cabra, Malahide and Shankill. Beyond those points they can't see anything coming into their area of control until they are close to entering their area of control.

They would not.

fundamentally because of course IE has both CTC, which is really a colour light form of a central semaphore power box and MAS in the GDA. I could never extract a reason the DART system wasn't integrated in the CTC or vice versa on my many trips to the control room at connolly

CTC has a screen and can see all the way to Great Victoria Street, its provided by Translink, its there just above the CTC suburban console

To really help matters the Suburban and Mainline signallers sit in different rooms which aren't even next to each other

IE using mph isn't an issue as the public don't need to know or make use of speed limits on rail etc. They could use knots or meters per second etc, makes no odds to customers.

Strange but true.

Both are called half inch, but were always different. UK is 15mm, Ireland is 14.7mm.

I think you'll find that you have that one assways. I'v been involved in construction for nearly 40 years and it's all metric we been using. All UK stuff is imperial.

And strangely enough Irish builders will still refer to things like "two be four", meaning 50mm x 100mm!

Rough? or Planed? cos that'll be different dimensions again...

Will IÉ be publishing their punctuality stats on the new route for November?

even if they don't their stats for every other route through Connolly will be screwed by the knock on delays (though I was only 4 mins late last night, which is an improvement, and by IÉ's definition, not late).

Any know what happens when Boombridge Station opens.
Will it be integrated?

More importantly will you need to carry a sidearm.

Broombridge was never closed (in spite of its appearance at times).

It just isn't on the the Phoenix park tunnel line, which runs further to the east.

Luas cross-city will be running from broombridge when it opens.

So that’s two major interchanges that are not integrated on the line. Heuston been the other.

I know people on here will disagree but it really limits customers options of where they would like to go.

I think people on here would agree with you completely.

n97 mini · 29-11-2016 03:34PM

I'd love to see a London Underground style map of the Dublin SHZ rail "network" as is, and then with potential interconnecting stations added where lines cross or run side by side.

BBridge will be integrated with the luas and can't be integrated with the PPT.

Heuston is (badly) connected with the luas and should have been connected underground to the centre decades ago.

Yup, I mentioned that a few posts up.

There were suggestions earlier in the thread that the Luas could have run a little further east and a station could have been added where the PPT line first(from Heuston) crosses the Dublin-Sligo line.

Neither are true.

Both are true according to the ministers answer to a question from jack chambers a few weeks ago. The Maynooth line has been put to the back of the queue around Dublin.

Apart from new stations not being safely built on curves, there's no handy unused railway to route the tramline further east then the existing one.
