The Ballybrophy/Limerick line is afficted by level crossings, particularly between Birdhill and Killonan. There are a very large number of accommodation crossings as well but oddly enough they seem to have more of an impact on this line than any other line. For instance there are plenty of accommodation crossings between Limerick and Limerick Junction as well and although the general speed limit on this line has been reduced from 80 to 60 mph it is still well above the 30/40 mph deemed necessary on long lengths of upgraded track on the Nenagh line.
The whole accommodation crossings treatment on the notwork is completely different. Between Cherryville-Carlow they have a 100 mph sign out for a short section before dropping an 80 mph to pass a crossings before another 100 mph. It's ridiculous on two fronts, one been signs are located so close to crossings and two I don't think a few miles less will change the outcome of any potential incident.
One section is 80 (1/4 mile), 100 (1 1/4 mile), 80 (1/2 mile), 100 (1 1/2 mile), 80 (1/2 mile), 100 (3/4 mile). That is over around 6 miles.....there is one section of about 5 miles (no crossing) and you can do 100, that's about the only time most drivers even bother.
It will never be possible to get rid of such crossings so are we going be left with a network capped at max of 80 on all routes (outside Cork, no such crossings) because of such crossings.
I get the safety aspect but surly procedure review with owners could minimize risks of higher speeds for the most part.
