The Barrow Bridge on the mothballed Waterford to Rosslare Strand railway is an opening bridge, allowing for shipping access to/from New Ross.
The bridge is currently inoperable (academic due to the mothballing of the line) due to a maritime bridge strike. Irish Rail have stated that as part of the repair/re-opening of the bridge, they plan to automate the opening of the bridge, allowing for control to switch to the National Train Control Centre in Dublin.
One wonders why there are not similar plans for the canal lifting bridge at Newcomen Junction in Dublin.
