Coldfield to Lichfield was opened in 1884) is shown as roughly hourly on weekdays, with additional trains terminating at Four Oaks approximately every 30 minutes. On Sundays five trains ran to and from Sutton. Trains to Wolverhampton and Walsall ran at irregular intervals on weekdays, with service of five trains to and from Walsall on Sundays. An interesting service was the New Street to New Street "circular" via Aston, , and , with two trains completing the full anti-clockwise circuit, but only one in the opposite direction. Most clockwise trains finished their journey at Vauxhall and . There was no Sunday service. Trains on the circular route are shown in the Summer 1939 London, Midland and Scottish Railway timetable as taking 43 minutes for the complete New Street-New Street circuit. Otherwise, the pattern of services in the months leading up to the outbreak of the Second World War had hardly changed since 1921. The London Midland Region timetable dated 10 September 1951 shows an irregular interval service of approximately hourly trains to and from Walsall and a similar service to Lichfield City via Sutton, with some trains running only as far as Four Oaks (tables 68 and 69). In the Summer 1963 timetable, by which time diesel multiple units were operating on both routes, there was a regular-interval service pattern throughout the day: on weekdays every hour to Walsall and Rugeley Town, and every 30 minutes to Sutton and Lichfield, with occasional trains still terminating at Four Oaks. After electrification, services to Walsall were operated by Class AM4 (later re-designated British Rail Class 304) electric multiple units. The 1970-1971 London Midland timetable (Table 9) shows a weekdays only service of regular-interval hourly trains throughout the day, augmented at peak periods with additional services. There was also one service, originating at Walsall, which left Aston at 0717 for Coventry via Stechford. (There was no corresponding service in the Walsall direction). The Sutton and Lichfield service was largely unchanged from 1963 on weekdays but there was now no Sunday service. The above patterns applied also to trains to and from Birmingham New Street, where all trains from Aston to Walsall and Four Oaks or Lichfield originated. Following the introduction of the Cross-City Line in 1978, Aston gained through trains to and from Longbridge via Birmingham New Street. The basic pattern was Lichfield to Longbridge and vice versa hourly throughout the day Monday-Saturday,
