From Tamar to Tay
Calstock viaduct (Bere Alston to Gunnislake)
At Bere Alston in Devon, a branch left the London and South Western Railway main line to Plymouth and curved across the Tamar to serve Gunnislake in Cornwall. The branch crossed the Tamar, which is still navigable at Calstock, in a deep gorge by means of a tall viaduct. Map Ref SX433686
Shillamill LSWR
A few miles further north in the Tamar valley, the LSWR Plymouth line cut through a small spur of land which the river skirted, at Shillamill. Map Ref SX464711
Horspath
The Great Western line from Oxford to Princes Risborough via Thame delved underground at Horspath, near Oxford. The tunnel is a single track one with a double curve in it, the centre being out of sight of both entrances. If you saw the earlier version of this page where I typed "Kidlington" above, apologies for the confusion :-). Map Ref SP576050
York Road (King's Cross)
A line left the Great Northern Railway at King's Cross in London and, using a separate platform there from the main station, dived underground to join the Metropolitan Widened Lines to Moorgate (Met). This platform or station was called York Road. During recent scaffolding works it has been just possible to get a peek inside the entrance. Map Ref TQ302833
