I don't think the majority of its target audience know what bullhead rail is. Or flat-bottomed. Or actually care.Can anyone identify which tunnel was used for filming the Box Tunnel scenes? I hope that people watching it don't think that the GWR main line still uses bull-head rail.
I did forget to put a smilie laugh after my last comment, which was supposed to be tongue-in-cheek.I don't think the majority of its target audience know what bullhead rail is. Or flat-bottomed. Or actually care.
Thanks for that. Another railway I have never visited.The interior shots apparently used Greet Tunnel near Winchcombe on the Gloucester & Warwickshire Railway.
