The great great grandson of Patrick Stirling, the engineer who designed the Stirling Single locomotive featured in the current production of the Railway Children at Waterloo Station, came to see the show this week.
The 66-tonne Great Northern Railway Stirling Single locomotive – dating from 1870 – arrived at Waterloo's former Eurostar terminal in June in readiness for the stage show which opened last month.
A 1000-seater theatre has been created on the platforms of Waterloo's disused international station.
The Railway Children is now booking till 2 January 2011.
