Watercress Line

Due to the COVID-19 emergency the Watercress Line Mid Hants Railway is temporarily closed to the public. The safety of our staff, volunteers and visitors is our most important consideration. You will know that the Watercress Line relies on ticket revenue to cover its operational costs, which currently work out more than £75,000 a month. Without money coming in from running services, the railway is eating into its financial reserves to survive. If you can help, please click on the Virgin Money Giving link below which allows you to donate a single amount or pay monthly if you're able to. You can also text WATERCRESS to 70085 to donate £10, texts cost £10 plus one standard rate message. Thank you for continuing to support us during this unprecedented situation. We hope to be able to welcome you back to the Watercress Line soon.

41312 - LMS Ivatt Class 2MT

Status Operational


An Ivatt LMS design introduced in 1946, 41312 was built in May 1952 at Crewe locomotive works and spent its entire working career on the Southern region. They were nick named Mickey Mouse tanks due to the placing of route indicator discs either side of the smokebox that then looked like ears.

41312 was first based at Faversham, then Ashford in June 1959, before being moved to Barnstaple Junction where she worked over the Torrington branch, putting in some appearances on the Ilfracombe and Exeter line.

In March 1963 she was reallocated to Brighton. In 1964 she moved to Bournemouth were she worked over the Swanage and Lymington branches. 41312 performed the last steam service on the Lymington branch in April 1967. The last 3 months of her career were spent at Nine Elms acting as a station shunter for Waterloo. She was finally withdrawn from service on the 3rd July 1967.
