What trucks are these?

Can someone tell me what type of trucks are under this DW&P loco?
Are they a Canadian truck?

Modified ARR B truck, no leaf spring,  CP RS23s were similar.

The biggest difference is internal brake cylinders. That's why they look so naked.

OK so Modified AAR B truck sounds good but who's truck is it. Is this then an MLW Montreal Locomotive Works design?
Next question is does anyone make this truck in N scale?

Forum member @mandealco showed some he made a few weeks ago, I think he made them out of the trucks that came with the RS-11...

Both. CN had scores of their RS-10 and RS18's delivered with the lightweight trucks, all from MLW, while the 15 DWP RS-11's were all delivered with the lightweight trucks from ALCO. Who's design? Hard to say but likely MLW since they were first applied to the RS-10. CN had a real thing for lightweight locomotives (lots of light rail branches), to the extent that their Mountains and Northerns were lightweights relative to other roads power.
Welcome to Ontario... we've got a tax for that.

   they are CFS Non Swing Hanger trucks,Dofasco had similar trucks also.
   they seemed to be at least 9' length,but could have been 9'4" length.
   the one that was looked over in Conklin Yard about 1990,matched the
   picture above.
    there was also an 8'10" version that seems to have been a DOFASCO
   truck.they are interchangeable with standard 9'4" Type "B" road trucks.
   there are pics out there with CP RS-3s thaty have 1 of each style truck
   under them.
   cant recall any model versions of either the CFS or DOFASCO trucks in
   plastic HO scale,maybe they have been made in Brass?
   did Minatures by Eric do a DOFASCO side frame kit at one time ?

  CN seemed to be the big user of CFS trucks.
  they were under F-M H10-44s,RS-10s,the DW&P RS-lls.
  would think they would be under RS-18s also,but havnt
  seen any pics for that yet.
  any other Canadian locos get these trucks ?
    DW&P RS-11s:
   built rather early in RS-11 production,but had several
  unique features for U.S. built RS-11s{ Mlw built RS-11s for NdeM}.
  1st was the CFS trucks,odd importing Canadian trucks into the
  U.S. when several Foundries could have supplied trucks.
  Dynamic Brakes in the Short Hood RS-10 style.no other U.S. RS-11s
  had this feature.all other RS-11s with Dynamics were on the long hood
  over the engine area.

I appreciate all the info gang now we just need someone to make these trucks.

Spikre, here's a shot of a CN RS18 for ya. http://www.rr-fallenflags.org/cn/cn3125jpa.jpg and later on it had a truck change. http://www.rr-fallenflags.org/cn/cn3125jpc.jpg
From looking through the shots on George's site many of them had there trucks changed around late 60's to early 70's.
Although I did find this shot taken in 1980 http://www.rr-fallenflags.org/cn/cn3743bgC.jpg and this one taken in 1986!!! http://www.rr-fallenflags.org/cn/cn3742ags.jpg
So some of them lasted for a while. Hopefully someone else can fill in the info of when and why the change happened.

The trucks were swapped indiscriminately according to 'CNR Diesel Locomotives - Vol 2' (Courtney, Goslett, Holland), with no discernible rhyme or reason.

     thanks for those pics.
   have also found a pic of a converted PGE RSC-3 to RS-3 with those
   trucks,and what seems to be a PGE RS-10.   
    then found a pic of what may be one of the DW&P/GTW/CV/GT RS-11s
   painted for a second hand owner.
   but havnt seen any CFS trucks under CP units yet.

I think the CP RS-23s rode on a version of those trucks....

   looking at an L&S RS-23 pic,ithe trucks seem to have Dofasco Script on them.
   but if an actual loco can be checked,that is always best.
   the RS-23 seems to have 8' wheelbase trucks.
   have seen the Dofasco script on a Blomberg truck under an Amtrak F40.
   is Dofasco still in operation ?

Sort of, the Dofasco plant now belongs to ArcelorMittal, however they got rid of the castings division a long time ago. The truck casting knowledge went to Atchison, which later became Bradken. Bradken still makes some Dofasco designs such as the Bombardier BiLevel truck (although slightly modified over the years).
Because why not...
