Something built 70 years ago does not provide context. I could for instance say there was a massive and quick building programme across Germany from January/February 1945, but it's wouldn't solve the housing issues here. The world has changed (sometimes better sometimes worse), whether you like it or not.
Woodbrook has been built and opened just as development started opening up, the Green Line was extended to Bride's Glen when it was a field (and now very much is not), same with Saggart, so there are several cases where things have happened for the regular passenger. Woodbrook cost €24m as a guide. As I said, Adare is a different matter and funded in a different way. There's also Galway station, Oranmore loop, Cork Area Commuter Project, DART+, Metro - all which funding of €3m would help but (particularly for the latter) not make much of an impact. The €3m will more than likely be recouped through the significant footfall for the week across the country, which if you lobby your local TD could then go to public transport funding. Or other services that are needed.
There's far more pressing concerns about public spending!
You're entitled to your opinion, and I'll leave it at that.
