  1. LMS2968 replied to the thread Will standard gauge steam railways ever be able to order a new loco ?.

    It would depend on the railway. On the SVR, which is the one I know, the tank engines currently in use are restricted to six-coach trains, not by what they can pull but the amount of water their tanks can hold. And during the season the SVR...

    Actually, David Joy's gear worked very well and gave, for the time, quite decent valve events. There was some minor alterations in valve events during running due to the vertical movement of the driving axle on its springs, but it was the LNWR...

    Better he never tried to do 90mph with a P1

    On a point of order, Mr Chairman, I doubt it would ride better than a 9F. In my experience, few men were fond of the 9s, but all agreed it rode like a coach. This possibly explains the reported 90+ mph exploits: the driver was probably unaware...

  5. LMS2968 liked 242A1's post in the thread Efficient use of Steam.

    As you were on Doncaster Station which is on the old LNER it might be best to consider the practice of this company. However LMS2968 very rightly points out that there is more to consider than the thermodynamically optimum. The long travel valve...

    Depends on the engine, the valve gear, lap and lead figures and a host of other things. Generally, the full regulator / short cut-off theory applied to the more modern locos, but there were other considerations than just the efficient use of...

    An option to make it worse?! I think in the event that happened you would look to build a new normal 9f boiler. The instances of preserved loco boilers being written off in their entirety have been few.

  8. LMS2968 replied to the thread A new-build BR Standard Class 3 is planned..

    The boiler was smaller than a standard 9Fs to allow space below for the Crosti pre-heater. When the Crosti drum was removed (which I think it was, rather than merely blanked off), the smaller boiler was retained. The lower steam raising capacity...

    Agreed. Otherwise you are into "that's the waggling lever that moves the rod that ..." which is no clearer than using the correct terms. Moreover, I suspect if you changed the names, you'd just end up raising hackles in a different group who want...

  10. LMS2968 liked Richard Roper's post in the thread LMS Patriot Project Updates.

    I agree completely. We are dealing with a piece of Engineering, which people will either know about or will not. If non-Engineers are interested, they will contribute anyway. The commentary was perfectly adequate, as has been said, because the...
