instrumental in the introduction of Automatic Train Control on the Great Western Railway. 1941 accident On 2 July 1941, an express train from Plymouth to Paddington hauled by No. 4091 Dudley Castle collided almost head-on with a freight train hauled by a LMS Stanier "8F" 2-8-0 at Dolphin Junction, 1 mile east of Slough. The express was in the process of crossing from the up main to up relief line via a diamond crossing. Five passengers were killed and 24 injured. The signalman was held to be at fault for allowing the express to cross in front of the heavy freight train (not fitted with continuous brakes) without ensuring that the latter could stop in time. 1994 accident On the evening of 2 November 1994 a Class 165 Turbo train crashed through the buffer stop of platform 6, after failing to slow down due to poor rail adhesion on the approach to the crossover. It is estimated that the train had only reduced its speed from to approximately at the time of collision, apparently skidding for some through three sets of points (which had approved speeds of on the relief lines, for the Platform 6 bay). Evidence gathered at the scene by investigators suggested that the train, had it not hit the buffers, could have continued for another . There had been light drizzle on the evening in question. This was only one of a number of instances in which Class 165/166 Turbo trains had overshot platforms and run through red lights. These incidents led to driver retraining and the teaching of defensive driving techniques during the autumn leaf fall season. The main contributing factor was the change of braking system from brake shoes (which effectively cleaned the wheel each time the brakes were applied) on the previous DMU fleet to disc brakes, which allow the mulch from the rails to adhere to the wheel, leading to poor rail adhesion. This also led to regular sanding of the rails on all lines affected. The station today In the Office of Rail and Road's statistics for 2017/18, the railway station has 5.544 million users every year making it the 88th busiest railway station in Great Britain. This figure does not take into account the 1.59 million additional users of the branch line to Windsor & Eton Central. The station is a short walk from Slough bus station and has a taxi
