    Greater Anglia Bombardier Aventras (Class 720): Technical discussion and introduction

    I note so far only 5-car 720's on stratford services in spite of longthened platforms at Stratford. Any idea what's preventing them being lengthened to 10-cars at the moment?

    Class 810 for East Midlands Railway Construction/Introduction Updates

    Based on Class 222 derated setting of 700hp per engine and allowing for appx 80% power at rail equals 418kW per vehicle or 2,089kW for a 5-car 222 - with all engines running. Do we know the overall weight of an 810 yet? In electric mode at least - the power application of an 810 will likely be...

    Class 730 LNR & WMR Delivery/test Updates

    From a performance point of view - comparing with GA 720's - it is the difference between a 30 second stop and one taking closer to 60 seconds - wh ih can be crucial in making up time when running late.

    Class 730 LNR & WMR Delivery/test Updates

    Re 730/1, the additional walk through space by having 2 plus 2 seating is a huge improvement over the 720's. But yes the seats could do with being a tad wider as a result. Not sure how the 3-car units compare in relation to installed power, but so far the acceleration recorded is no better than...

    Looking for 0-60 times for all consists of trainsets that run in the 2020s

    Yes indeed. That's why data has to be collected on numerous runs to create a 'cluster' of data. There will be some runs where drivers don't give it the full beans and runs where drivers will. Assuming you are recording data on reasonably level track , then other factors such as damp/ slippery...

    Does anyone know the rough acceleration of the London Underground D78 Stock trains in m/s^2?

    That just about sums up technically what I would explain from my journeys. They seem to pull away quite smartly up to about 25mph and then the acceleration rate starts to tail off quite noticeably. THi wasn't an issue in the central core with short distances between stations and low maximum...

    Looking for 0-60 times for all consists of trainsets that run in the 2020s

    There isn't a list of 0-60mph times in the Railway Performance Society (RPS) archives as far as I am aware. The archive contains mainly journey logs which will usually contain timings and speeds at various measured locations (sometimes mileposts and kilometre posts) and other known measured...

    Looking for 0-60 times for all consists of trainsets that run in the 2020s

    I'm in contact with the author of the 0-60 series in Rail Express magazine and have a number of timings of my own for different consists. It's not possible to publish anything here from that magazine here. You can message me and I'll see what I can do to help you get the info you are looking for.

    Train design: Where has it all gone wrong?

    The acceleration curve is not constant - so the maximum acceleration rates quoted for older stock may not be diectly comparable. Today, both Class 745 and 720 can reach 100mph in under 2 minutes, compared to around 2 mins 40 secs for a Class 360 and somewhere between 4.5 to 5 minutes for a CLass...
