At 19¾ miles, the West Somerset Railway used to be Britain’s longest independent
When the narrow gauge (1’ 11½”) Welsh Highland Railway extention to Porthmadog opens
in 2011 it will exceed the length of the WSR. I am having trouble finding an accurate
length as reports seem to vary but it appears to be about 25 miles.
When complete the WHR will join the Ffestiniog Railway at Porthmadog Harbour station
and it will be theoretically possible to have a continuous run of almost 40 miles.
However, there are no immediate plans to run through trains on a regular basis as
the WHR has a larger loading gauge than the FR.
The West Somerset Railway is now Britain’s longest standard gauge (4’ 8½”) independent
