I visited Whatley Quarry again in July 1984 after the construction of the new line, although the tunnel under the road with the 'S' curve still remained between the quarry and the new exchange sidings.
A view of the BR exchange sidings with 47094 just arrived on a train of empties.

The view through the tunnel under the road with Thomas Hill diesels Nos.3 and 2 working in tandem about to enter with a loaded train from the quarry.

Nos.3 + 2 leaving the tunnel, they will stop just after the first wagon reaches the post on the left of the photo and uncouple from the train.
47094 coupled on to the loaded train for departure to the BR network.

No.4 a Vanguard diesel hydraulic supplied new by Thomas Hill in 1968. The locos are now in the yellow livery of A.R.C.Ltd., the current owners of the quarry.
Nos.3 + 2 propelling the empty wagons brought in by 47094 through the tunnel to the quarry loading hoppers.
followed by No.4 with more empty wagons.
Main line trains from Whatley Quarry are now handled by Mendip Rail with their own Class 59 locos. The quarry has recently acquired a Class 08 shunter rebuilt as a battery loco.
