Re: Re: Luas Central – Which Route?
You just can’t get enough abuse can you ?
1 excavation: the foundations for the tracks , would have to cope with hundreds of tonnes. (Compare foundation for a ten story appartment block to a bungalow and you get the picture).
2.utilities diversion , this requires digging up everything up, leaving you to start from scratch , not with an old rail line, that has just had it’s tracks taken up.
3. In the same way as a winding road in the wicklow hills will occasionally have gravel spread over it’s length as surfacing , while a motorway has purpose designed tarmacadam to a high spec in order to cope with lorries. The same thing applies to the metals tracks and everything below : two grades , one cheaper , one not so cheap.
4.The electric system. : why did they need change the dart electric system using your logic ? (the dart upgrade cost 170 million). I will tell you why. if there are metros comming every 90 seconds at peak time, and each metro weight 10 to 20 times a tram , then you have to be able to deliver a whole lot more electricity safely. So you wouldn’t suggest that the wiring in a home was sufficient for a factory , would you ?.
5. Bridges: deciding you need a bridge that can cope with a lorry instead of pedestrians is NOT simply changing the specs.
6. between sandyford and the canal there are 2 at grade junctions. They will simply be closed. total cost : no euros!
7. a large part of additional expense went into blasting the rock cutting between stillorgan and ballaly stops, so that it could accomodate the much wider metro.
as someone with an ego the size of robert maxwell , i know how hard it is to be wrong, but it is ok thomond.honestly
