I'm sure everyone's seen the fuss about Scotsman being banned from the Borders Railway due to gauging issues and then suddenly permitted again.
So here's a quick question: Network Rail must have data about the gauge of the Borders Line because Tornado and UoSA have run on it recently.
Do they have to do a fresh survey for every engine that runs on it, or can they simply take the dimensions of Scotsman and compare it to the two similar design of engines for which they already have gauging data and make an informed decision that way?
And if it's not being discussed elsewhere, how were they suddently able to change their mind about it last minute?
