This geocache is hidden beside the old Drewton railway tunnel which was a part of the previous Hull to Barnsley railway line. It is a simple puzzle cache all you must do is gather information from the description.
The posted coordinates are of the eastern portal, you do not have to visit them.
The Drewton Tunnel Then
The eastern portal of the tunnel back when it was in use
The Drewton tunnel is the longest of the three tunnels within this section of the Yorkshire wolds, to the west are two much shorter tunnels, The Weedley tunnel and Sugar-loaf Tunnel. Both are now out of use although Weedley tunnel is used by cars for the nearby estate.
It was built by navvies who owned a temporary camp, under the name of Riplingham, adjacent to the third airshaft (hence the name of the area in east Yorkshire which has kept the name).
It stretches an impressive length of 1 mile 354 yards and first opened to rail traffic in 1885.
The Drewton Tunnel Now

Nowadays, the Drewton tunnel is one of the longest, disused, railway tunnels in England; it is no longer used for carrying goods but it does have more uses than you may think…
- Science experiments take place within the tunnel as part of a university experiment into ground water.
- A colony of bats use the tunnel as their home
- Modern day explores venture into the tunnel to take pictures of the engineering
- Quarrying takes place at the western portal, even though the portal is now filled in, valuable building materials are extracted.
It was unfortunately, also, very short-lived, only being used for 79 years up until 1964.
The Future of the Drewton Tunnel
Apparently, There are plans to create the world’s longest subterranean rollercoaster, running the entire length of Drewton Tunnel… although, we’ll let you look at the date this story was added to the internet and you can make up your own mind

The more likely option is that the tunnel will be claimed by landfill, at the moment the colony of bats is preventing such a thing happening but who knows what the fate of the tunnel will be.
Though venturing into the tunnel is dangerous, the internet has provided us with a virtual tour of the tunnel, just visit this link for more.

The Little Weighton Cutting Then
The Little Weighton Cutting and the Accommodation Bridge
The Little Weighton cutting was an 83-foot-deep cutting in the Yorkshire wolds, east of the Drewton tunnel to accommodate the hull and Barnsley railway.

The Cutting and the Location of the Accommodation Bridge
Unfortunately the cutting, like the tunnel, only lasted 79 years closing in 1964. It only has one use nowadays and that’s to store household waste, the entire thing is slowly being consumed by landfill.
