Why is it that after over five decades of preserved steam locomotive operation nobody has solved the long term issue with steam leakage from the cylinder drains of Stanier locomotives? It was a problem with steam in the 1950s and 60s that was attributed to poor maintenance but that is no excuse today. Black five 4-6-0 45305 demonstrated the issue superbly as it pulled away from Quorn and Woodhouse with the 10:00 Santa Special to Leicester North on Saturday 12th December 2020.
