Motorway services - old Otis and ancient Otis lifts

The southbound side has some old Otis lifts, but I suspect these have been refurbished in 1999 when the whole place had a revamp. The northbound side is the most interesting. There is a derelict viewing gallery which has been closed for sometime due to fire regulations. The two lifts are completely original. Only one works, but what a classic! Although, do you notice the lift has fully stopped moving when the doors open? It's quite usual for old Otis lifts to continue moving whilst the doors open. The hold open timer has decayed (probably an old capacitor style timer) to ONE SECOND OR LESS! Lovely old lift this one, it's a shame about the 2nd floor viewing gallery - would love to have explored that!
