GWR Wycombe branch line at Horspath. Old tunnel, both ends found and sealed up. 1 of 3, linked below

No drone as too windy but dry and warm day so off I went.
Noticed a tunnel on the old map the night before.
Bricked up so I did not get in but I stuck with making the video on the old line at Horspath.

The Wycombe Railway was a British railway between Maidenhead and Oxford that connected with the Great Western Railway at both ends; there was one branch, to Aylesbury.
The Wycombe Railway Company was incorporated by an act of Parliament passed in 1846. The act authorised the construction of a single line railway from the Great Western Railway's Maidenhead railway station, then located close to the site of the current Taplow railway station.
In 1852 construction started; the first section to be built was between Maidenhead and High Wycombe.
In 1862, the Wycombe Railway opened an extension from High Wycombe via Princes Risborough to Thame. In 1863, it opened a branch line from Princes Risborough to Aylesbury.
In 1864, it opened an extension from Thame to Kennington Junction on the GWR line between Didcot and Oxford, thus finally completing its route to Oxford.
In 1963, British Railways closed the section between Princes Risborough and Kennington Junction to passenger traffic.
The line between Kennington Junction and the former Morris Cowley station is open for freight traffic to and from the Mini (BMW) factory.
The tunnel was used from 1864 to 1963 is 450m in length and was told up at the road on the bridge by someone, it has bats in it now.
