During those early years, the railway became famous
and people came to ride on the 'Smallest Public Railway
in the World'. The locomotive fleet was extended to nine
main-line express engines and a fleet of luxurious
coaches were built.
The war years took their toll, the line being requisitioned
by the War Department — they even created the only
miniature armoured train in the world — and was used
extensively during the building of PLUTO (Pipe Line
Under The Ocean) which fuelled the Allied invasion force.
