Reference, please, regarding the 2-6-6-2 = Mallet? I can’t find a single one. All the Whyte notation listings I’ve been looking at (only five or so so far) do not give a name for this configuration (and one gave the name Mallet to the 2-6-6-4!).
OTOH, you’re right, I’m sorry for offending all Pennsy fans for including obscure things like Folies, and not including the Duplex!
Apologies - a “Mallet” type locomotive is an articulated compound locomotive (It uses the steam twice - high pressure in one pair of cylinders, and lower in the other). Though the mainstay of these were of the x-6-6-x type (in the US) they could potentially be of any configuration (UK railways had some 0-4-4-2’s).
As such, ANY compound articulated could be classed (generically) as a Mallet. However, there are also articulateds that used hi-pressure steam in both sets of cylinders (notably the UP 3900s and 4000s) and as such are not a part of the generic “Mallet” class.
I hate to ask this, bit who makes the PRR T-1 model nengine and what does it cost? Kchronister, when I saw the PIC I went D-M and some other’s word’s I cant post here. It just blew me a way. I have never seen anything that looked like that before!
Thanks for the answer’s and MOST IMPORANT the great pic, pic of the benches make me sick when I look at mine. But I am getting better, I just bulit my first tree to night! Got to start somewhere.
Here is my faviort at this point.
I am fickel, I was hot for Santa Fe F’s, E-6’s then Dash 8 and FP-45’s. But for what ever reason I have fell for the Monon Line and BL-2’s. Maybe because I am from Ind, or plus I love the stricking colors of the Black and Gold. To think I was calling this engine ugly, well sort of still is, but I like driffrent.
Hope to see way more PIC, looking for more diesels PIC. But keep the steam PIC coming.
