Interesting. Was this true of all Brunel's broad gauge lines? That
would have meant that high(ish) speeds on broad gauge wouldn't have
been compatible with the comfort (and possibly the safety) of
passengers. Do you know if Brunel realised that later?
I think it was discovered quite early on and most of the broad gauge
were converted to sleeper type track, on broad gauge.

No, it was just that they stopped having vertical piles. If the GWR
hadn't retained its longitudinal sleepers, they would have had a much
easier time when they finally abandoned the broad gauge in 1892.
As it was, they had to cut all the cross-transoms to allow one rail
*and* its longitudinal sleeper to be moved inward.
