A London Underground 'S' Stock train.

A Class 7F at Grosmont Station, North Yorkshire Moors Railway.

A Class 43 HST in BR Blue and Yellow livery, c.1970/80. Class 43 43002 still runs in this livery, and is used on the Great Western Mainline.

A Class 43 HST in GWR Green livery, c.2015/16. This livery has only been applied to some engines, as they are to be replaced in 2020/22.

A Class 345 in TfL Rail livery, soon to become the 'Elizabeth Line'.

A Class 390 (390049) 'Pendolino', used on the West Coast Main Line.

The stations on the Cotswolds Line today are as follows (not nessecarily in order): Oxford, Hanborough, Finstock, Shipton-Under-Wychwood, Kingham, Ascott-Under-Wychwood, Moreton-In-Marsh, Honeybourne, Evesham, Pershore, Worcester Shrub Hill, Worcester Foregate Street, Malvern Link, Great Malvern, Colwall, Ledbury and Hereford.

Services on the Cotswold Line are operated by Great Western Railway (GWR), and use the following rolling stock: Class 43 HST, Class 150, Class 153, Class 158, Class 165, Class 166, Class 170, Class 172, and Class 800. The Class 800 services are only 5 carriages as the platforms at the stations along the route can only take 5-6 carriages. Even the Class 43 HSTs do not fit on many of the platforms.

The Class 68 diesel-electric locomotives are used throughout the country, but the Chiltern Main Line is one of the only places where they are used on regualr passenger services. Built in 2014, the last batch was delivered to the UK in 2017 and they have been running up and down the Chiltern Railways routes ever since. The Class 68s replaced the Class 67s which originally hauled the services.

The Class 68-hauled services are some of the only ones of their kind in the country, with a normal locomotive and a normal set of carriages. Because of this feature, they are like the old British Rail Class 37s, which did the same job,only 50 years earlier!

Even though Chiltern Railways do own some Class 68s, Direct Rail Services (DRS) do lease some 68s to run certain passenger services. One example of this is class member 68009 'Titan', which operates along the Chiltern Main Line in DRS colours.

Here is 68009 in Direct Rail Services livery. It sometimes works alongside Chiltern-liveried Mark 3 coaching stock and Driving Van Trailers (DVTs). Because it can also operate freight services, like all Class 68s, it can work anywhere needed.

The London Underground, operated by Transport for London (TfL), is the railway system that runs around under London. There are two main sections: 'The Tube', the slightly newer, tube-shaped tunnels, and the 'Sub-surface' lines, the District, Circle, Hammersmith and City and Metropolitan.
