| Footage description: | Shots of the Advanced Passenger Train on a test run. David Crecraft the programme. Shots of the APT in testing. Crecraft in the APT testing shed begins discussion on APT resonance testing. He introduces Khalid Sammoui engineer in charge of resonance testing. Sammoui discusses details of the resonance test on the APT bogey suspenion which is in progress. Shots at the test bed of the test in progress. David Crecraft in the control room explains how data from the resonance test is monitored and analysed. He points out and gives details of the apparatus used. David Crecraft with a stator and rotor of the APT hydrokinetic brake. He explains how the hydrokinetic brake works. Crecraft examines a complete APT brake on a test bed. He points out the transducers on various parts of the brake and explains what they measure. Crecraft introduces an actual brake test . Martin Collins in the control room runs through a brake test. He points out all the monitoring devices, explains how the test is conducted and carries out the test. His commentary explains what is happening as the test proceeds. John Monk introduces a sequence on metal fatigue research at British Rail. Bob McLester, head of the Fracture Mechanics Section, explains the need for metal fatigue studies at British Rail. He defines fatigue failure and shows a fractured test piece. McLester shows how a test piece is tested in a fracture apparatus. John Monk explains how a fracture test is carried out and monitored. Shots of a fracture test in progress. David Crecraft stands-next to the APT and sums up the programme. Credits (over shots of APT on test run). |
