Watch Online Free HD Solarmovies. This 4K video features around an hour of footage of the steam locomotive No. 70013 ‘Oliver Cromwell’ on a special charter day on the Keighley & Worth Valley Railway. The charter day, during March 2018, shows the engine and its goods train at various locations along the line. We have produced the film in the order that the clips were taken, and it shows well how a charter day works, with the train making multiple passes of each photo point the train stopped at.
