    Charles Thompson Ltd and CTL Seal were linked 5 years ago but are now completely separate companies. They are working together on our boiler project. Their web site does need updating

  3. Sheff liked Kirk Oswald's post in the thread North Yorkshire Moors Railway General Discussion.

    Is said membership secretary part of the railway's salaried staff likely to be in the loop regarding the bought and paid for awards scam, or are they a volunteer being hoodwinked by the Park Street Polit Bureau? If the latter then I don't think...

  4. Sheff liked Bikermike's post in the thread P2 Locomotive Company and related matters.

    That is good news, that is part of the original strategy, so it does imply that things are keeping (belatedly) to plan. Fascinating as to where you draw the line with modern tech. If building it from the ground up, would you even bother with...

  6. Sheff liked W.Williams's post in the thread P2 Locomotive Company and related matters.

    Helpful. Presuming FEA is stressing, and there will be a fluids analysis to help with valve events... If so, timing the valves for optimum flow through the ports, probably the first time anyone has ever done that for steam. That alone will...

  7. Sheff replied to the thread GWSR General Discussion and Operations.

    I suggest that a valid comparison in terms of contemporaneous main lines would be the GCR London Extension? This was also built post the pick and barrow era. I’m not aware of any history of structural failures there? Not sure what conclusions...

  8. Sheff liked Dan Hill's post in the thread 6024 King Edward 1.

    I think those images appear to come from an account on YouTube, who posted a YouTube short of the loco moving. Glad to see 6024 in steam again. Personally I hope it does end up in matching GWR livery to 5029, because (in my opinion at least) the...

    So this para on their website is obsolete? “Since the acquisition of Seal Engineering (now CTL Seal) in 2009, our operation also includes the design and manufacture of bespoke fabrications, structural steelwork, heavy precision machining,...

    No they are completely separate companies

  11. Sheff liked acorb's post in the thread The 10A Allocation.

    I think we established a long time ago that 'profit' and 'business sense' have not been at the forefront of recent decision making. If it were they would have prioritised fitment of CDL for the Jacobite several years ago, rather than putting it...
