Few years ago I see this nice Trainmaster article:

https://www.pnwc-nrhs.org/Trainmaster20 ... 014-05.pdf

Now I stumpled on this info again on the NCRY (where the engine steams up right now)
and on wikipedia.

But even when it is repeated several times on internet it become not more true!
That locomotive was outshopped in November 1927 for Walter A. Woodard Lumber Co.
in Cottage Grove, OR.
See the first picture still at ALCO's Schenectady factory.

The second picture show the manufaturers portrait of wood burning Heisler c/n 1558
manufactured March 1928 for Fischer Lumber Co. in Marcola, OR. So this one is five
month younger! Even not the last wood burning Heisler, this come in summer 1928
but it go to a mexican customer.

Surprisingly the two lumber company are only 30 miles apart.

I do not know if this is the last wood burner for america (america means the USA, this did not include Canada
or Mexico:-)) but certainly later then the Alco 67544.
In my opinion there could be some small industrial wood burning locomotives for owners
who have easy or free access to firewood build by Davenport, Porter or Vulcan on a later date.
But I have no access to this information.

I can't say about Porter but Davenport built their last wood burner for a US customer in 1914.

Well, that Heisler certainly is an eye-opener to me. A superheated 2 trucker and with inside admission valves. I would have to guess that this one is a much later example. Would anybody please be able to come up with the c/n? Thanks in advance.

As stated above: "The second picture show the manufaturers portrait of wood burning Heisler c/n 1558 manufactured March 1928 for Fischer Lumber Co. in Marcola, OR."

Thanks John, I failed to read the entire post.

Hallo Tom,
you right. Very exciting locomotive.

According to my research this is actually the first one with inside steam admission piston valves.
Still use of the "cornered" steam pipes not the "rounded" of the later build.
Plus when you look closely the engine has only steam brakes. No air brakes in 1928!
Look like that company use a lot of brakeman on their flats, skeletons or disconnects.
2 pics operating you can find here:

Complete data:
cn 1558 class 50-8-36 march/1928 Fischer Lumber Co. #3 Marcola, OR

After that Heisler build 3 more with OUTSIDE steam admission:
cn 1562 class 90-12-40 june/1928 Weyerhaeuser Timber Co. #101 Longview, WA
cn 1565 class 80-12-38 summer/1928 Cia. Maderera De Durango #4 El Salto, Mex
cn 1566 class 65-8-40 summer/1928 Rapid City, Black Hills & Western #7 Rapid City, SD

Just in the late summer 1928 they switched to INSIDE steam admission
for the remaining manufacture of locos ordered with superhead with this one:
cn 1569 class 90-12-40 september/1928* White River Lumber #3 Enumclaw, WA
*(Kline descripe build 9/1928 but shipped 2/1929)

Here is what Fischer reported for the 1930 survey: 6 miles RR, 6% max grade, 20 degree max curve, 1 geared loco, 12 pair disconnected trucks. No need for air brakes.

Thank you for the added info John.

In 1930 Fisher was averaging 100,000 board feet a day so between 10 and 15 cars of logs. By 1937 they had 12 miles of track and 3 locos. They were last mentioned in 1939.
