Looks as if Irish Rail need to urgently revise their contingency plans during periods of significant signalling disruption. It is clear that DART operations are not compatible with other than minor signal failures as typically such failures render coded signals inoperative resulting in DART movements being restricted to a maximum running speed of about 10 mph.
While such working over short sections (say between two signals) may be practical, DARTs crawling along at 10 mph over lengthy sections of line simply collapses the DART service and massively delays other services. Yet another operational disaster for Irish Rail with attendant misery for their customers.
