@quillmaurer6563 Well the wider the gauge the lower the centre of gravity so the more pleasant the trip and smoother the cornering. Isambard Kingdom Brunel actually wanted a Broad Gauge for his GWR line from London to Bristol, and some of it was built and engines ordered but they turned out to be unsatisfactory and it was built in Standard Gauge instead. It would have been interesting though because the Locomotives being much bigger would have been an incredible sight.

@quillmaurer6563 Yes, comfort, carrying capacity, and cornering, are the main advantages, but of course it carries a higher price tag for construction. The high speed lines all have to be built as straight as possible to allow the high speeds safely, that's why we have to build a completely new line for HS2, to eliminate as many curves as possible. It makes sense to have a standard gauge for ease of equipment manufacturing and what we are using is probably sub optimal but too late to change.

Changing the gauge now would be horrifically expensive. Every bridge, tunnel and station would need to be modified as well as moving all the track the electricity lines if electrified the signals, everything., not to mention every train and carriage. It would be more economical to build an entirely new railway. Train journeys would be more comfortable for passengers though with a wider gauge, it's just not practical.

I doubt Hitler went to the trouble of orchestrating an accident. If he had finished with you he would just have you shot, after all who was going to complain about it?
