Island Line has been brought to a halt with all trains between Ryde and Shanklin suspended this afternoon (Saturday).
South Western Railway say that due to an electricity supply problem, train services on the Island are currently suspended.
2 fire appliances were called to Rowborough Lane on the outskirts of Brading at around 17:00 with fire crews inspecting an electricity substation near the junction with Carpenters Road, alongside the railway line.
Crews then re-located to Harding Shute, where a sub-station was found to be on fire. The fire had spread to a nearby field too, which was extinguished using 2 hose reel jets.
Disruption on the network is expected until the end of the day meaning trains are unlikely to run again until tomorrow morning.
