So looking at it, it has taken 103 years to raise the speed by 13MPH, about a 10% increase.
Not really an earth shattering project.
I reckon that if they took the original design, stuck decent tyres on it, maybe a more efficient boiler, and they could have done it on a much smaller budget.
To me that looks like modern technology being worse than a relic from the past, and as such a total and disasterous failure, and nothing to be proud of.
