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, it is owned by Network Rail and is operated by Great Western Railway.

Frome station was designed by J R Hannaford. 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.

Frome station was originally on the Wilts, Somerset and Weymouth Railway, a railway that linked the Great Western Railway (GWR) at Chippenham with Weymouth. The line was authorised in 1845, was acquired by the GWR in 1850, reached Frome in the same year, and was completed throughout in 1857. The original route of this line is that of the loop line through Frome station. This line forms the basis for today's Bristol to Weymouth route.

A branch from Frome, authorised by the same act of 1845, opened to freight traffic in 1854, originally as a broad gauge mineral line to Radstock with a station at Mells Junction (renamed Mells Road in 1898). It was converted to standard gauge in 1874 and opened to passenger traffic in 1875. At Radstock this line connected with the Bristol and North Somerset Railway, providing a more direct route to Bristol than that provided by the Wilts, Somerset and Weymouth Railway. Sidings were created in Frome to service local industry: in the 1870s for the Cockey gasworks at Welshmill and the cattlemarket in the town centre, and then in the 1890s for the Cockey engineering works in Garston.

For the remainder of the 19th century, the GWR's principal route from London Paddington station to Exeter, Plymouth and Penzance was an indirect one via Bristol Temple Meads (the so-called Great Way Round). However, in 1895 the GWR directors announced that new lines were to be constructed to enable trains to reach Exeter, Plymouth and Penzance in a shorter time. This involved improvements to the Berks and Hants Extension Railway and the Wilts, Somerset and Weymouth Line, together with the construction of the Castle Cary Cut-Off, which was opened from Castle Cary to the existing Bristol to Exeter line at Cogload Junction in 1906. This transformed Frome from a station on a secondary north to south line, to one on a main east to west route. The route resulting from these improvements and extensions forms the current London to Penzance line. In 1933 a by-pass route was constructed, enabling through traffic to avoid Frome station and the junction with the Radstock branch, and leaving the station on a looped branch as at present.

In 1925, there were nine or ten trains per day between Radstock and Frome with just two on Sundays. In 1956, this had reduced to only three, with none on a Sunday. The line to Radstock was formally closed in July 1988 by the removal of two rail lengths at Hapsford. The first part of the branch remains open to carry aggregate freight trains from Whatley Quarry. Colliery traffic from Radstock closed in 1973. This section of line is mainly used by Mendip Rail; Freightliner Group will take over the line in November 2019. After the branch near Great Elm to the quarry, the rest of the route to Radstock is now the route of National Cycle Route 24, otherwise known as the Colliers Way.

In February 2014, the station was refurbished. In December 2014 a plaque was installed at the station commemorating a journey made from Frome to London in 1912 by Leonard Woolf to propose marriage to writer Virginia Stephen. The journey to make the proposal, which was initially refused until a change of heart, was the start of one of the greatest literary partnerships of the twentieth century.

On 24 March 1987, a passenger train and a freight train were in a head-on collision due to the freight train passing a signal at danger. Locomotives 33 032 and 47 202 were severely damaged. Fifteen people were injured, some seriously.

Great Western Railway operates services approximately every two hours between Bristol Temple Meads and Weymouth which also serve stations such as Bath Spa, Westbury and Yeovil Pen Mill. Beyond Bristol, some of these trains serve Gloucester or Cardiff Central. Great Western railway also operate limited services between Frome and London Paddington. South Western Railway operate infrequent services between Yeovil Junction, Yeovil Pen Mill and Frome to and from Westbury, Salisbury and London Waterloo.
