Built by British Rail Engineering Limited (BREL) at its Derby Litchurch Lane Works, the British Rail Class 158 Express Sprinter is a diesel multiple-unit (DMU). They were built between 1989 and 1992 to replace many locomotive-hauled passenger trains on key long distance cross-country routes.
An improvement on previous incarnations of the Sprinter series, the 158 offered luxuries such as air conditioning, an on-board payphone, power-operated interior doors, a toilet in each carriage, and provision for a refreshment trolley service. They also offered a top speed of 90 miles per hour (140 km/h) and a generally more comfortable ride for passengers. They have a range of up to 1,600 miles between refuellings.
Built for British Rail, they are currrently operated in the UK by, Abellio ScotRail, Arriva Trains Wales, East Midlands Trains, Great Western Railway, South Western Railway and Northern.

The Wales Coast Path (Welsh: Llwybr Arfordir Cymru) is a long distance footpath which follows the whole of the coastline of Wales. It opened on 5 May 2012, and offers a 870 mile long route from Chepstow in the south to Queensferry in the north.
Wales is the first country in the world to provide a dedicated footpath along its entire coastline. The Path runs through eleven National Nature Reserves and other nature reserves, including those managed by The Wildlife Trusts or Royal Society for the Protection of Birds (RSPB).

Route 8 of the National Cycle Network, also known as Lôn Las Cymru, runs for 436km (271 miles) between Cardiff and Holyhead via Brecon, Builth Wells, Machynlleth, Porthmadog and Bangor. Between Machynlleth and Porthmadog there are alternative routes - one coastal, the other inland via Dolgellau, Coed y Brenin and Trawsfynydd.

The National Cycle Network is a network of cycle routes. It was created by the charity Sustrans Link (Sustainable Transport), aided by a National Lottery grant.

Many routes aim to minimise contact with motor traffic, though 70% of them are on roads. In some cases the NCN uses pedestrian routes, disused railways, minor roads, canal towpaths, or traffic-calmed routes in towns and cities.
