      Back in the 1800 there was a fixed boiler in the round house that surplied steam that was true for most industries.
      In the 1930 those was mostly swiched put for compressors. If they wanted to move a loco just a few meters or so they simply presurized the boiler with shop air/steam.
      If the boiler is att full pressure they can run quite a bit with no fire.
      Also smaler yards have locos with only tanks that was only presurized by shop air/steam.

      I will however admit the 3-cylinder locomotives were an absolute pain to maintain, so for live steam this is ok, "BUT", it would have been great to put the third-cylinder in place as a dummy as most would not really see it not working anyway.

    • @timspiers6225
      @timspiers6225 3 года назад +3

      I don't see how the middle cylinder would be impossible to maintain. The 9000s had Gresley Gear so all the levers would be on the front and therefore accessible. If roller bearings were used wear would be kept to a minimum and slop should not develop. Between the frames there would only be the drive and the crank axle. After all it is 15" gauge. There are many 5" and 7.25" gauge 4 cylinder GWR Kings and LMS Coronations in the UK. I see that they have decided not to go for superheating.

      @@garthhentley8870 he's talking about switches on a rail line. A check rail is the rail that keeps the axel wheel on a train from jumping the track at a switch or when a train is crossing a bridge in case of derailment. A swingnose crossing or moveable point frog is a device used at a railway turnout to eliminate the gap at the common crossing (a.k.a. frog) which can cause damage and noise.
      With all those wheels each having a flange it makes it impossible to turn on sharp turns or switching tracks without some way of having each turn individually or having the inner wheels flangeless

      Do you see the big and small cylinders up the front? The purpose was to use the steam twice as it cooled. You would not get this from compressed air. Steam locomotives were developed over 60 years and compressed air would have been used if it was more efficient. Perhaps the compressed air could run at a higher pressure if nothing broke.

    Czy generator -> prąd -> sprężarka elektryczna -> silnik parowy może mieć większą sprawność niż sam kocioł parowy ?

      Yeah that's what I meant. 4-12-0 Lol. My bad.

    Wow! Nice! No "blindrivers"? Are you lubricating the cylinders?

    I find something oddly amusing about watching a steam engine run without a boiler. I look forward to seeing it run on steam.

    So here in the comments i see there's a bit of controversy regarding Gresley valve gear. So my only question is: is this type of valve gear that bad?

    That's an incredible amount of fabrication there. At 3:18; comparing the red-striped driver with the one behind it, the counterweights within the drivers are considerably different sizes. Why is that?

    Better apply screw air compressor than piston type, more quiet n power saving.

    That have to be one heck of a compressor... or they spent 15 minutes to pump the tank prior to set off
    Looking closer that is two compressors, and well, one large airtank.

      If you hafta ask, I doubt you can truly understand... The tools and skills cover a wide range!! These guys are at the top of their class! I'm an old machinist. To do this they must work all day most every day. Beautiful work!! This video is three years old. A new one is available.
