Class 165 Turbo trains were introduced in 1991, initially between Marylebone and Banbury. These improved passenger comfort and enabled journey times to be reduced; frequencies were increased, with an hourly stopping service to/from High Wycombe and hourly semi-fast service to/from Banbury. In 1993, Marylebone-Banbury services were extended to Snow Hill, calling at Leamington Spa, Warwick, Solihull and Moor Street, initially on a two-hourly frequency, increased to hourly the following year, when a Dorridge call was added. In 1995 the Jewellery Line was re-opened to allow Worcester line services to be diverted from New Street to Snow Hill; this allowed some of Chiltern's weekday peak-period services to be extended beyond Snow Hill, first to Stourbridge Junction and then to Kidderminster.
