I've been living in Sallins for the past 8 years and really like it. I used to do the commute but have now got a job locally.
The train service is reasonable, but is due for some radical improvement, most likely when the Kildare Route project is completed....expected by 2009, if they are to be believed and will double the number of trains.
There's a new complex being built beside the train station that will have a supermarket, hotel etc and that looks like it will be a very well finished complex, judging by what's done so far.
The development of a shopping centre beside Millbank looks like it's finally starting. They've begun to dismantle the old meat factory and as far as I know the development will have a Super Valu style supermarket and 17 shops and a pub/restaurant. There was plans for a hotel and marina but I have my doubts they will be built, especially as the other development has a hotel.
There is a by pass planned for Sallins...both Castlesize park and Sallins Pier developments have green space running through them to allow for it....from what local councillors are saying it may take for this to be done first before any money is spent on improving the look of the village....Clane has come on leaps and bounds since it's bypass was completed. I do know there are plans to put all esb cables underground, new paving etc down by the canal but they are just plans at the minute. The development of the village has really only kicked into gear recently, up to now it's been mostly just new houses.
There's also a planning application in for a new church and community centre just gone in.
Hope that helps.
