The first section of the Great Western Railway, between the original station at Paddington and the original station at Maidenhead (moved and renamed Taplow), opened on 4 June 1838, but although trains stopped at Slough, there was no actual station: tickets were sold at the Crown Inn. This was because the Act which authorised the construction of the GWR contained a clause which forbade the construction of a station within 3 miles (4.8 km) of Eton College, but it did not explicitly prevent trains from stopping for passengers. Following the repeal of the relevant clauses in the GWR Act, the first proper station at Slough opened on 1 June 1840. The arrival of the railway led to Queen Victoria making her first railway journey, from Slough to Bishop's Bridge near Paddington, in 1842. Later, a branch to Windsor & Eton Central was built for the Queen's greater convenience. Nowadays, the journey time between Windsor and Slough is six minutes.
On 8 September 1884 the original station was closed and replaced by the present station.
The station was rebuilt in its present form, situated 200 metres (220 yd) to the west of the old site. The buildings have survived largely intact, although some of the waiting room buildings on the island platform were demolished in the 1970s before the station was Grade II listed.
"Station Jim", based at Slough railway station, was a Canine Collector for the Great Western Railway Widows and Orphans Fund from 1894 until his death in 1896. After his death he was stuffed and placed on display in a glass cabinet with a collection slot. Station Jim can be found on Platform 5, and there is an inscription, written after he died, that describes his life story. Take a look if you are there passing through and pop some coins in. He no longer barks for them however.
The station has been undergoing works recently, with a new overbridge built at the east end of the platform finsihed a couple of years ago. The station is now fitted with overhead wires for CrossRail. The Cache location is just a short walk from an ideal train spotting location, if you are tall enough!
