Golfa Bank is a particularly steep bank on the Welshpool and Llanfair Light Railway. The bank is nearly a mile at 1 in 29, which in its day, was the steepest section of the Cambrian Railways worked by passenger trains and is still a challenging climb. The line travelling up the slope is curvy, to make the climb easier. Golfa summit is 630 ft above sea level, meaning the locomotives have to travel from about 350 ft above sea level at the bottom of golfa bank, meaning they climb 280 ft in 1.5 miles.The locomotives had to be built specifically to manage the bank, due to its steepness.
There is a halt at the top called Golfa Halt.
