Passengers at Alexandra Palace station got a welcome surprise earlier today, when the world’s most famous steam engine, the Flying Scotsman 60103, passed through.

The engine, built in Doncaster in 1923 came through the station on its way to Southall, as it makes its way to the South West of England for a series of tours. After leaving Alexandra Palace, it passed through Finsbury Park, before branching off to Camden Road and Hampstead Heath along the London Overground line to Southall.

Despite being scheduled to briefly call at the station, the engine, which was only pulling one carriage, chugged past surprised travellers.

The locomotive is back in service after a decade-long overhaul was completed in 2016. Among the work that took place on the engine at the National Railway Museum in York was getting a new boiler certificate.

David Winskill said: “There wasn’t much fanfare. Nobody at the station seemed to know it was coming, even the station staff didn’t know about it.”
