When I started at Millerhill in 1980 the down hump was still in use, I agree with poggie man, it was mind numbing work.
All the shunting work was in the accomodated link, drivers with medical conditions etc which meant they had to be doublemanned. Every driver on the down hump pilot took their PNB in the "Alpha", a pub 5 mins walk away
There used to be 6 shunting locos at Millerhill, now there's one on hire to Network Rail who now own the yard. Early '80s there was the down hump pilot, down yard pilot, four in total in the up yard, two general pilots, reclamation pilot and "McPhee's" pilot (the Pway shunting job).
