While Brunel was still in Bristol, and with the Avon Bridge project stopped or going slowly, he
became aware that the civic authorities saw the need for a railway link to London. Railway
location was controversial since private landowners and towns had to be dealt with. Mainly, the
landed gentry did not want a messy, noisy railway anywhere near them. The Duke of
Wellington (of Waterloo fame) was certainly against it. Again Brunel showed great skill in
presenting his arguments to the various committees and individuals. BruneI built his railway
with a broad gauge (7ft) instead of the standard 4ft 8½in, which had been used for lines
already installed. There is no doubt that the broad gauge gave superior ride and stability, but it
was fighting a standard.

Brunel’s ready acceptance of new ideas overpowered good engineering judgment (at least in
hindsight) when he advocated the installation of an atmospheric railway in South Devon. It had
the great attraction of doing away with the locomotive and potentially could deal with steeper
gradients. Since this connecting arm had to run along the slit, it had to be opened through a
flap as the train progressed, but closed airtight behind it. Materials were not up to it, and this
arrangement was troublesome and expensive to keep in repair. After a year of frustration, the
system was abandoned. Brunel admitted his failure and took responsibility. He also took no fee
for his work, setting a good professional example.
