You're absolutely right, duttonbay, it is Chesney. Well done!
In 1916, a Standing Parliamentary Committee discussed a proposal to construct a cross-country line between Chesney and Dookie, which would have joined the north-eastern and Goulburn Valley lines.
The famous Flanagan and Allen song to which I referred, which made a passing reference to railway infrastructure, was "Underneath the Arches", referring to the arches of the Friargate Railway Bridge in Derby. The arches still exist, although I believe trains no longer go over the viaduct.
(Valvegear, when you first mentioned Telford, I assumed you must have been thinking of the actor Telford Jackson. But he was Australian, not British.)
Your turn, duttonbay. And my apologies to anyone who goes to bed tonight with an earworm.
