Did Britain make errors in developing the railway as there were no examples to follow
Unfortunately there
were examples for the first public railways (such as the
Liverpool & Manchester) to follow : the industrial wagonways. George Stephenson, bless him, adopted the track gauge to suit the typical colliery wagons of the time, and the loading gauge to suit a typical road carriage. I guess he saw an economy of employing existing wagon and carriage builders to manufacture railway rolling stock. There was also still a vestage of the mind set from the collieries with wooden plank tracks, and plateways such as the horse-drawn
Surrey Iron Railway, that railways could and should accept wagons straight off the road - early bi-modal.
Also unfortunate was Brunel's choice of an extreme opposite wide gauge, which did cause problems on tighter curves. I think that if Brunel had gone for something like 5'6" or even 6 ft there would have been a chance of it winning the gauge war. Even Stephenson admitted in later life that he wished he had chosen something "a little more", probably thinking of 5 ft.
