The following link is about the Stanley Steamer motorcar of a century ago.  The story goes the company offered $10,000 to anyone who would dare to open the throttle all the way…and never had to pay out.  Nobody had the nerve to try it!

To understand something of the finally-irreducible limits on effective static and/or dynamic balance of driving-wheels of external-combustion steam locomotives, the following link by Stephan M Dick on dynamic augment, or the pounding sometimes completely (!) out of line of steel rails, is helpful:

L F Loree

by Preserved Wook

The following biographical precis is from the online pp of:


Leonor Fresnel Loree was born in Fulton City, Illinois, on 23 April 1858 and died in West Orange, New Jersey on 6 September 1940. He was a civil engineer and railway executive.  Educated at Rutgers College, he worked both for the Pennsylvania Railroad and the US Army Corps of Engineers.  In 1884 he became engineer of maintenance of way, Indianapolis and Vincennes division of the Pennsyvania RR, and in 1888 in its Pittsburgh division.  This division, with its heavy traffic in ore and coal transiting a railway of many curves, was considered a severe operating problem.090809 Mrs Harlestan Corbett Lewis and L F Loree  
     Loree increased operating efficiency, introducing the lap siding.  His continued professional progress led to him being made general manager of Penn Lines West in 1896, and fourth vice president in 1901.  Early in 1901 the Pennsylvania acquired a controlling interest in the Baltimore & Ohio to which Loree was elected vice president.  His innovations and leadership resulted in much improved efficiency and co-operation with other railroads. 
     Loree moreover introduced Walschaerts valve gear and Mallet locomotives in the first decade of a new century, its bright promise not yet blighted by late-modern (more…)

110909 diagram showing inside-admission steam piston valve at start-point of power piston return-stroke


[diagram showing inside-admission piston valve at start-point of power piston return-stroke — the valve piston continues to the right, letting in steam to the righthand face of the power piston, driving it to the left.]

This Wikipedia valve gear link is topflight:


It makes clear that although “greatest power is achieved by keeping the inlet valve open throughout the power stroke (thus having full boiler pressure…against the piston throughout the stroke) [that] peak efficiency is achieved by only having the inlet valve open for a short time and then (more…)

America’s Lost Trains

082309 Hiawatha 3 streamliner www.steamlocomotive.com 3

Do You Remember?
Burlington president Ralph Budd stepped off the Burlington Zephyr after its record-breaking run and proclaimed, “It was a sweet ride.” Most Americans agreed. Marjorie Wigton, who worked as a “Zephyrette” hostess on the Burlington from 1936 to 1941, described the impact of the streamliners:

“If you are brought up in a small town, small towns are close to railroad tracks, you are used to steam engines. Here are these beautiful white puffy clouds and panting trains going by and their special whistles. It was just a part of everyday life…a dozen times a day you would see a puffer going by. And then…all of a sudden here is this shiny beautiful thing…The whole town was out…thousands of people. It was like a butterfly coming out of a cocoon. It was this beautiful…silver train…not dirty…just…whoosh. It was a beautiful thing.”

In a 1997 interview, Zephyr engineer Glenn Corniels, who started his career shoveling coal as a steam train fireman, recalled the Zephyr’s speedy route from Chicago through Aurora, Illinois to Savannah. “No stops… had to blow the whistle 144 times between Aurora and Savannah… I remember, 144 times!”

Do you have memories of streamliner trains?

San Francisco Examiner, Jan. 11, 1952

The Westbound Pacific’s California Zephyr was derailed seventy-two miles west of Grand Junction, Colo. last night.

Early Associated Press reports said none of the 140 passengers bound for San Francisco aboard the sleek streamliner was injured.

The Rio Grand Railroad office in Denver said all cars were derailed. The locomotive did not leave the tracks. A relief train was sent from Grand Junction to take over passengers. The accident was at Vista siding, barely over the Colorado line.

On January 8, 1952, my mother and I boarded a train in Washington D.C. enroute to Chicago to catch the California Zephyr. We were headed for California to visit my (more…)

[If you are like me and plan to win a lottery in order to have the Lima Company or somebody build you a full-size replica of a Y6b, then maybe you have a few unanswered questions on your mind.  In addition to whether you should maybe win another lottery in order to buy yourself your own coal mine, I mean.  Such as what all (!??!!) can possibly go wrong with your new locomotive?  The following Federal inspection requirements are detailed to put it mildly.  And guess what?  Somebody in “The Gu’mint,” as Old Wook’s people say back in Maine, must know something that Senator Gore and the global warming folks do not…like maybe one day that these oldtime locomotives will be making a comeback.  And soon, too!  Because why?  Well, for what it is worth — and you can see this for yourself — the regulations below are dated…2003! — ERS]
