Iarnród Éireann has appealed to truck drivers to be aware of their vehicle height after a rise in the number of bridge strikes across the rail network.
In 2014 there were 85 bridge strikes across the network, however this year to date there have been 68 such incidents.
The DART network has seen the largest increase in the number of collisions with 25 already in 2016, compared to 12 this time last year.
From a low of 72 bridge strikes nationally in 2012, Iarnród Éireann said the increase in bridge strikes is worrying.
A spokesperson for Iarnród Éireann said: "The message has to get through. It is basic safety for truckers to know the height of their vehicles and the bridges on their routes."
The company said bridge strikes can cause significant delays to both rail and road services, as it must carry out a structural assessment of the bridge before allowing trains to pass over following a hit, and road traffic can end up severely backed up.
Iarnród Éireann has also released a video to alert road users of the dangers of hitting bridges and the damage that it can cause.
