pete_mcfarlane Posted January 15, 2022 Share Posted January 15, 2022 4 hours ago, Andy Kirkham said: I'm perplexed by the rod emerging from the top part of the cylinder. Presumably it actuates the piston and must somehow gain its motion from the inside valve gear, but it's not clear what it's attached to at the rear end. I think there's some kind of rocker arm - you can see it better in these photos. 2 Link to post Share on other sites More sharing options...
rockershovel Posted January 15, 2022 Share Posted January 15, 2022 I'd guess the valve gear on an early contractors loco like that would be Stephenson or possibly Hackworth? Neilson definitely produced some odd looking locos 5 2 Link to post Share on other sites More sharing options...
Steamport Southport Posted January 15, 2022 Share Posted January 15, 2022 11 hours ago, Hroth said: Leader as a replacement for M7 tanks? In hindsight, a "stodgy" Q1 tank or Leader built as a diesel would have been better solutions. Correct. The M7 were suburban tank locomotives which worked the outer suburban routes of the ex LSWR. Later replaced by LMS Fairbairn Tanks and BR 4MT 2-6-4Ts. They certainly weren't branch line locomotives. Jason 1 Link to post Share on other sites More sharing options...

He didn't hate diesels, he thought that steam had more to offer/ could be developed beyond what the mid 1940s state is the art was. 1 Link to post Share on other sites More sharing options...

Steamport Southport Posted January 16, 2022 Share Posted January 16, 2022 (edited) They're the same wheels found on early Manning Wardle locomotives. I always thought it was for balancing as the second "unused" crank was usually blind.

Nearholmer Posted January 16, 2022 Share Posted January 16, 2022 Have you never cross-threaded a crankpin, and wondered what to do next? Well, those old-time designers built in a spare hole. 2 Link to post Share on other sites More sharing options...

eldomtom2 Posted January 23, 2022 Share Posted January 23, 2022 Not mentioned yet, I believe - the experimental conversion of an N class to use mechanical vapor recompression.

pete_mcfarlane Posted February 12, 2022 Share Posted February 12, 2022 Rack locos always look odd when they are on level track. But that is definitely weird.
