The crew were<br />not happy about the heat. <br /><br />Yes they do look misshapen. <br /><br />Turns out that Garretts were still in the optimization stage even <br />late in the game. For all the other styles there were critical <br />dimensions (height, width, length, and weight) that were maximum <br />performance limiting. Garratts has a little room for expansion.<br />Example despite the size of the firebox at one end if the boiler<br />is long because it can't be made a greater diameter the amount <br />of heat extracted at the stack end is low. Its an efficiency <br />battle.<br /><br />Unlike the Mallet which swing out and makes for balance issues at <br />speed in a curve the Garratts straddle in, a better direction for <br />balance. Both cases have issues with tight turns and clearances.<br /><br />Look at all the large engines be they Decapods, Triplex, Shay, <br />Mallets, or Garratts complexity is a standing matter of fact. <br />Even the modern oil burners still have the same challenge of <br />greatest possible tractive effort for the gallon of fuel or <br />lump of coal.<br /><br />Eck!Eck!https://www.blogger.com/profile/13890237094647111653noreply@blogger.comtag:blogger.com,1999:blog-7924773307171301256.post-38190573584128644822016-01-02T07:14:49.328-05:002016-01-02T07:14:49.328-05:00I would have thought it simpler, on at least the A...I would have thought it simpler, on at least the Aussie one, to have the cylinders closer to the boiler. Less piping and it might have made the blastpipe more efficient.Comrade Misfithttps://www.blogger.com/profile/15404477636451308763noreply@blogger.comtag:blogger.com,1999:blog-7924773307171301256.post-75519542706470502702016-01-01T23:31:25.789-05:002016-01-01T23:31:25.789-05:00Never even heard of this style before.

Seems an unnecessary complication to have to provide steam to two motive sections from a central boiler, but...<br /><br />And,,yes, it don't look "right".CenterPuke88https://www.blogger.com/profile/17770056621255249861noreply@blogger.com
