Pictures emerged on Linkedin earlier this week of Iarnrod Eireann's new Kirow crane. This was on test at Portlaoise Rail and Sleeper plant, but actually was delivered around 4th October 2021, having slipped beneath the radar until now (despite it's size). This vehicle is a Kirow KRC500 Multi Tasker, which carries RIV number 99609 419900-6. It also carries "900" which would appear to be it's Iarnrod Eireann fleet number.
