Frome railway station serves a largely rural area of the county of Somerset in England, and is situated in the town of Frome. The station is located on a 1.5 miles (2.4 km) long branch line which loops off the main line railway, which carries services on both the Reading to Taunton line and Bristol to Weymouth route. Most of the trains which take the loop line in order to serve Frome station are on the Bristol to Weymouth route, and most trains on the Reading to Taunton line by-pass the station on the main line. The station is 22.25 miles (36 km) south of Bath Spa on the Bristol to Weymouth line, and is operated by Great Western Railway. Frome station was designed by J R Hannaford and opened in 1850. It is one of the oldest through train shed railway stations still in operation in Britain. The unusual station structure consists of a 120 by 48 foot (36.5 x 14.6 metres) timber train shed, supported by 12 composite trusses with a span of 49 feet (15 m). The station has two platforms, one of which is now unused due to the line being made into a single track. It is now a Grade II listed building.
