Not every event that happens uses worst-case data. In any case, while I don't know the actual class of rail where this emergency stop happened, this wiki article[1] suggests that most mainline track in the US is class 4, which allows a max of 80mph for passenger trains.
Out of curiosity, why do you mix metric and imperial in the same context? Stopping distance in metric for a speed in imperial?

- Symbiote 11y agoBritish usage is a mess, they were the units I found. I didn't really think about it. I also can no longer find the table of stopping distances I found this morning. The official rules for driving cars in Britain have the same daft combination of units: https://assets.digital.cabinet-office.gov.uk/media/559afb11ed915d1595000017/the-highway-code-typical-stopping-distances.pdf https://assets.digital.cabinet-office.gov.uk/media/559afb11e...
- gsnedders 11y agoFWIW, the British railway still uses miles and chains for measure.
