the station. A canopy similar to the one for Clevedon trains was built for this bay, and for passengers at the end of the westbound platform. On 1 January 1876, the Bristol & Exeter was amalgamated into the GWR, who took over the running of the station and services. In 1879, the Clevedon branch was converted to standard gauge. This followed a scheme throughout the GWR to convert its tracks from broad gauge to mixed gauge. The last GWR broad-gauge train operated on 20 May 1892, after which all tracks were converted to standard gauge. The conversion of the Clevedon line coincided with the opening of an engine shed for branch traffic. A turntable for Cheddar Valley trains was built at around the same time. In 1889, there were 12 weekday trains along the Clevedon branch, and three on Sundays. Heyday and decline By around 1900, there were between five and seven services operating daily along the Cheddar Valley Line, with a mixed mail train on Sundays. Traffic was to increase from 1901 with the opening of the Wrington Vale Light Railway. Although this line joined the Cheddar Valley Line at , most services continued to Yatton. In 1901 there were four passenger trains per day and one goods train, which increased to five passenger trains per day by 1903. The line was known for the transport of mushrooms. By 1910, there were 18 daily services along the Clevedon branch, four on Sundays. A GWR pagoda hut was built in the 1910s at the east end of the eastbound platform, but this was removed some ten years later. By the 1920s Yatton had 40 staff employed, including a boy selling chocolate and cigarettes, and issued almost 60,000 tickets. Traffic on the Clevedon branch was still climbing, now up to 21 services on weekdays and five on Sundays. However, despite this success, there were some problems. Better road transport was reducing traffic along the Wrington line, and the main line was stretched to capacity. To combat this latter problem, goods loops were laid either side of the station – east for 1.25 miles to Claverham from 6 April 1925 and west for 1.75 miles to Huish level crossing on 26 May 1925. The station itself however remained a two-track pinch point. The Wrington Vale line closed in 1931, with traffic having dropped to only two trains per day with no Sunday
