In 1988, a temporary third platform was built at Port Sunlight station to allow a number of steam-hauled specials to run to and from Stork Margarine Works over the May bank holiday. Passengers were not allowed to alight at the other end. I did the trip twice.
A temporary station at Amlwch was also built in 1992 but only saw a very small number of special trains in 1992 and 1993. Passengers were at least allowed to alight.
On the Llangollen Railway, Corwen East station was opened in October 2014, closed in November 2018 and dismantled in early 2019.
