Network Rail blames “slippery rails” for mass cancellations and delays across the network.
Services between Leeds, York, Ilkley and Skipton were worse affected, with many trains cancelled at short notice and remaining services badly delayed.
Network Rail said delays, which they later attributed to “poor rail conditions” were likely to last all morning.
Despite the chaos, weather forecasters said Yorkshire was set for a pleasant autumn day, with skies clearing in all areas after isolated outbreaks of early drizzle. Temperatures will easily reach double figures, with an unseasonably high 12 degrees in most areas.
