Dublin Train Delays Causes: Bomb Alerts, Stray Animals and Sun Glare Drove Thousands of Hours Lost

dublin train delays causes now include a wide mix of unusual and external factors, with newly released figures showing nearly 2, 000 hours of disruption across more than 7, 500 affected services in 2024 and 2025.
Dublin Train Delays Causes: What the Figures Reveal
Data released under Freedom of Information legislation details how incidents ranging from bomb alerts to sun glare repeatedly stalled services over the past two years. The rail operator’s incident log shows thousands of trains were delayed by miscellaneous, unusual, or external obstructions, underscoring how even a single event can ripple across the network.
One example: in 2024, a single fallen tree triggered 6, 400 minutes of cumulative delay — 106 hours — across 251 different services. The largest single disruption last year stemmed from a medical emergency on board, which resulted in 8, 736 minutes of delay across 623 services. Trespass on the lines emerged as a persistent problem; in one 2024 incident alone, 590 services were collectively delayed for about 113 hours due to people on the tracks.
Other recurring hazards included animals — from livestock to domestic pets — straying onto lines, requiring trains to slow or stop until tracks were cleared. Bridge strikes, where vehicles collide with railway bridges and trigger safety checks, were another regular source of disruption, delaying almost five hundred services in 2024.
From Trespassers to Vandalism, Stones and Bridge Strikes
Antisocial behavior and vandalism continued to weigh on punctuality. The incident log cites children throwing stones at trains, objects left on the tracks, and debris that obstructed overhead power lines. Some cases were more unusual but still consequential: one person sat with legs over the platform edge, while others interfered with safety equipment or placed objects in door runners. Serious graffiti required at least one train to be taken out of service.
Behavior on board also caused knock-on effects. “Unauthorized disembarkment” and passengers holding doors open led to additional delays. There was even one instance of “scutting” — clinging to the outside of a carriage — which, while brief, still disrupted operations.
Bridge strikes remained a steady challenge, typically forcing trains to wait while structures were checked or made safe. Together with trespass, animals on the line, and vandalism, these incidents accounted for a significant share of the cumulative minutes lost.
Weather, Hazards and Other Unusual Triggers
Bomb alerts, fires near railway lines, and landslides were logged among more serious hazards that halted or slowed services. Weather compounded reliability pressures: fog, lightning, storms, flooding, and snow all contributed to delays affecting dozens of services at a time. Even strong sun glare, which can impede driver visibility, was cited as a factor, illustrating how environmental conditions can be as impactful as mechanical or human issues.
Collectively, these dublin train delays causes show how diverse and sometimes unpredictable disruptions — from medical emergencies and trespass to weather and infrastructure strikes — can cascade into thousands of hours of lost time across the network.
