To celebrate the return to traffic of our sole-surving Apple Green 4-6-0, B12 8572, the M&GN Society organised a special 'thank you' for Society members on Thursday 8th March, 2012.
Invited guests included, contributors to the overhaul, contractors who carried out works on the locomotive, dignitaries and members of the press. Alongside 8572, the J15 was back in traffic.
The J15 had undergone a retube over the winter to enable it to run in its centenary year. Built in 1912, the locomotive was reliveried into LNER Black, numbered 7564 to mark the occasion.
