All the debate about the NRM made me have a look at the NRM`s website Quite interesting what it says about the APT-E now residing at shildon
APT-E
(Advanced Passenger Train)
Collection Building Paving the way for high speed rail travel in the UK as we know it today, the APT-E was an experimental tilting train developed by British Rail during the 1970's and early 1980's. Powered by gas turbines, the APT-E achieved a new British railway speed record when on 1975 it hit 152.3 mph (245 km/h). After several delays, funding its entry into service became increasingly difficult and the project was eventually moth-balled.
Unless I've entirely missed the boat and correct me if i`m wrong Kit but was the APT-E ever going to enter revenue earning service as that's what the blurb above states
