Double-headed Compound Mallet Steam at the Niles Canyon Railway
Вставка
- Опубліковано 11 вер 2024
- For the 150th Anniversary Celebration of the Transcontinental Railway Promontory Connection, Niles Canyon Railway runs a special excursion train featuring double-headed Compound Mallet steam engines: Clover Valley #4 and “Skookum” Deep River Logging #7.
Engines featured:
Deep River Logging “Skookum” #7
2-4-4-2 Mallet, Baldwin, built 1909
(from Oregon Coast Scenic Railroad)
Clover Valley Lumber #4
2-6-6-2T Mallet, Baldwin, built 1924
These Compound Mallet steam engines have a very special designs: they have two trucks, each with their own pistons and rods. The rear one receives the high pressure steam engine directly from the boiler, and then the exhaust steam powers the front piston. This double usage of the steam is more fuel efficient. This also gives them a very high tractive force for their size. They were typically used in logging operations where the articulated trucks are ideal for the tight curves and the high adhesion/tractive force is ideal for the hilly terrain at low speed (typically up to 30 mph... for comparison NCRy runs its excursion trains at 10-20 mph).

Check out the "whistle symphony" at 4:12, it's quite something :-)

I love mallets locomotive
Maybe one day #7 can visit the little river railroad in its little river railroad livery and could triple head with #1 and the restored 110
Nice video
Glad you liked, thanks for watching!
@@SPNGLovato18 Nice! I see you have some track side videos at Brightside, Sunol, etc. These are cool.
Raphaël Moll yup
Awesome video, keep em coming!! A plus
Glad you liked it. The 1:1 scale is awesome :)
Thanks for watching :)
Let's get things correct. The Skookum came from Deep River Washington where it rolled off the tracks in 1955 avoiding the scrapper's torch and then it went to Snoqualmie, Wa, and laid in the brush for years till a new owner took it to Mt. Rainier Hist. railroad for partial rebuild and then down to Tillamook for finishing.
Thanks for the clarification.
This locomotive (Skookum) began it’s work in Tennessee where it ran for a short time on the Little River RR and Lumber company(Townsend, Tn) numbered as Engine 126. It was sent back to Baldwin because it couldn’t negotiate the tight curves of the line, with Townsend’s logging company ordering the even smaller #148 to replace it. 148 performed well, but sadly never survived the scrappers torch. I hate scrappers!
Awesome Video:) Did Skookum & Clover Valley #4 stopped for any run-bys on that day?
Not for that trip. This was before the "fan day" event with the scheduled run-bys, and they were apparently still trying to figure out what they could get out of Skookum.
Well that explains why Skookum blows its whistle after #4's whistle. Skookum ran quite well on May 11th until it experienced some safety valve issues later in the day:(
Number for air compressor Pipe exhaust sounds a lot like a cab forward
TexasRailfan21 which one, I know it’s clover valley lumber #4
Didn't know they built a switch at Verona. When will they get to Pleasanton?
It is PLA's goal to reach Pleasanton with the NCRy. It takes a lot of members and volunteers effort to diligently lay down track.
@ I grew up in Pleasanton. There has always been a political issue with the city council not wanting the line going into the city limits. Was that resolved?
@@darthnate117 Sorry I wouldn't know about that.
It may be awhile, Pleasanton had fought the railroad coming into Pleasanton for years. I know, I used to live in Pleasanton.
@@MrEricmopar I'm curious. What was the reason why?
roooooooooo!,,,,
Skookum is actually a Baldwin, not a mallet.
Skookum is a mallet type built by Baldwin. Baldwin is the manufacturer. A mallet is a type of articulated steam locomotive, and this one uses compound steam.
I’m just making the point that skookum, being one of the last 2-4-4-2’s and one of the last baldwins in existence that the headline should be just that.
If you search 2-4-4-2 the only videos that come up are of skookum or a saddle tank Baldwin 2-6-6-2, I forget it’s name because I don’t think it’s as cool.
This is awesome.. but ya wanna know what would be better? S i e r r a R a i l w a y # 30
Please enlighten me because honestly I have no idea which engine you're talking about. I'm not aware of PLA having Sierra Railway #30 these days, do they? It's not on the roster. Edit: found it here... plasteam.ncry.org/SRY30/menu30.htm in a page dated from 2012 with no further update after she was sent to Oregon Coast Scenic Railroad.
Alexi Lauto I prefer the mallets but that would be cool if Sierra railway 30 will run
