Hastings Diesels' 511-mile DEMU marathon from Hastings via the Midland Main Line to Nottingham and the High Marnham test track.

The Megawatt Valley Venturer is typical of Hastings Diesels' ambitious railtours. Leaving Hastings at 06:07 with stops along the Hastings line to Tonbridge, the ten-coach train of units 1013 and 1001 ran via Bromley South and Clapham Junction to the Midland Main Line, diverting via Corby, Oakham and Melton Mowbray to reach Nottingham by midday.

Passengers could spend the afternoon in Nottingham or stay aboard for a 97-mile round trip via Mansfield and Shirebrook to the High Marnham test track, a former colliery and power station line now used by Network Rail for testing. The train returned to Hastings at 23:08.

Fares were £95 to £102 in Standard and £122 to £129 in First Class, with reduced fares from Bedford. Hastings Diesels plans a similar pattern for 2027 with a short January trip and longer outings in April, June and September.

Which side to sit

Hastings → Nottingham and High Marnham Test Track

The highlights are structures the train runs through or over, such as the Hastings line tunnels and the Harringworth Viaduct, so either side works.

Classes of travel

StandardFirst Class
Before you book: charter trains depend on locomotive availability and Network Rail engineering work. Steam can be swapped for diesel at short notice, so check the operator’s terms for what happens then. When you book, ask for a seat on the side we recommend: most operators allocate seats but will note a preference.
