Navan Rail Line

There should be a station where it crosses the N3, so all the busses from Cavan and Kells can transfer passengers to the trains.

Irish Rail are hiring for the Navan line at the moment.

I mean near Navan.

I don’t see the benefits of using the old rail alignment in Kilmessan. Yes, there are two road bridges in Kilmessan, however, if this rail line is to be electrified, are the existing bridges suitable i.e. is there enough vertical clearance for an electrified service?

I also think, too many years will be wasted in court challenges of CPO's for the hotel and for these 15 houses (Although I think there’s more than 15, that would be affected). In relation to the hotel, the rail line would be going through the middle of the grounds of the hotel. I know the hotel, and have gone to a wedding there. They use "The Turntable" area for the wedding ceremony. For them, I think their whole business model would be destroyed.

What would this even cost, (I'm totally throwing figures out there) 15 houses at current market value, so say €350,000 to €400,000 plus (I assume they should get) compensation for moving too, so I'll say €100,000 to €150,000. And then there's the hotel, what value would it be? So CPOing 15 houses could be around approx. 6.75m to 8.25m and the hotel maybe 2m or 3m, that's about 9m to 12m and then, the existing bridges will probably still need upgrading.

So if we are going with that alignment, we will need a location for a station, so if you’re buying the hotel outright on a CPO, it could be a good location for a station again, however, I’m unsure if the original building would be suitable as a modern station and demolishing it, would, I guess, be out of the question.

I mean where the line cuts the N3 at the LC near the Blackwater Retail Park.

What would be the advantage providing a 2nd transfer station further away from Dublin? And why go to the expense of building a 2nd motorway connected station when there's a perfectly good one already at the M3 Parkway?

M3 Parkway is the perfect location for a hub for local and regional bus services serving this part of the country. It as close to Dublin as you can get but completely avoids the traffic chaos of Dublin and is rail connected right now. The fact that it's not being exploited for this purpose is wasteful.

Maybe it’s a bit controversial, but some of the alignment changes make less sense, like this:

The old bridge at Bective still survives yet the line is being rerouted to avoid it, seemingly for a single shed. I can somewhat understand avoiding Kilmessan but it hardly makes sense to not use existing infrastructure to preserve a garden and shed.

I never argued against removing a shed. That's very different to what you proposed.
