A major extension to the Dart network that's to serve new neighbourhoods in west Dublin has been delayed for at least four years.
The move has been described as "contrary to best international practice" by one transport expert.

Delighted to see the Elgar Encyclopedia of Transport and Society published today.
I authored Chapter 56 which defines decarbonisation of transport.
It is great to be listed with my international peers in this encyclopedia.

The transport investment plan is out, it looks to fund all the projects we have come to know over the years.. No new investment in Luas, bar the 4km Luas Finglas line.
If you include the €2bn for Metrolink the PT & Active travel vs Roads ratio is 1.4:1

My 4th year students present projects on decarbonisation of transport at 10am. They have lived experience in how far we have to come: I got a 7:20am email from a student whose 6:53am bus didn't arrive, meaning they won't make it for 10am. Happy World Sustainable Transport Day.

At a meeting on Friday I was reminded of how much work we need to do in Ireland to modernise and upgrade our existing rail network. Looking at the statistics, you can see how much work we need to do to even get to the EU average of approx. 57%.

My 2 cents in the article "the money would be better spent on extending Luas lines and delivering new urban rail services in our regional cities."
