Okay, where do I send it?  Pay up   :D

(why Inkaneer?  Did I miss something?)



Max, great looking engine, but it is difficult to see if the tender is complete.  :)

Yup, dummy, fully unpowered tender. The other problem is those side rods are always going in and out of sync with each other.  :P

Ha, the funny thing is I had to pull out the first engine and see how I did it.  Building the complete class of engine is reserved for the UP FEF, only 15 more to go! :o

Had to jump in...
The T1 was designed to operate from Harrisburg to Chicago, hence the relatively short wheel base. Many of them worked the slopes of the Alleghenies on a regular basis. The machine could develop 6500 HP at close to 90 MPH and easily top 100 on Lines West with a full train of pullmans. On the "racetrack" sections of Middle and Pitt divisions they had no trouble meeting the 70 MPH speed postings. The duplex drive was an attempt to use smaller, more powerful cylinders while avoiding the reciprocating mass of the main rods used on any eight coupled locomotive. The mechanical problems centered around the valves, which were actually a more efficient design but limited by the metallurgical technology of the time. Wheel slip was less a problem of tractive effort and more of an issue of too much throttle applied too quickly. A T1 could, in a sense, "lay rubber in all four gears". Spinning drivers at 100 MPH is no small feat. The critters were the muscle cars of railroading.

50 of the type served from their inception in 1942 until 1952...Ten years is not long compared to earlier classes like the L1 and K4 which were still in use in the mid-50's. Yet their careers were not much shorter than many of the other locomotives built in the 40's. SP's AC cab-forwards didn't last much longer. Nor did the N&W J's. Diesels proved so cost effective that even relatively new locomotives went to the scrappers torch. They were all born too late. By the end of World War II land based steam propulsion was a dead issue in the U.S. Development or improvement of any of the postwar steamers was a waste of time.

The T1 was designed for a specific role, high speed passenger service. Lacking the versatility of other PRR classes like the J's, M's and even K's they could not be adapted to lugging heavy freight, helper service or any other grunt work. The T's were sleek, fast and powerful but steam locomotive technology in any form cannot compete with the labor/maintenance cost, versatility and availability of diesel electric locomotives.

Of course it's a subjective viewpoint, but I rather fancy those shark-nosed speedsters.

Man...that is terrific stuff. 
I am especially impressed when it leans into that helix and effortlessly drags the train up and around.

Looks great, guys!   What if there were a brand of commercially available assorted, powered steam tenders...

Here's a Clerihew about Ed. K.

Ed Kapucinski
Every night, he plants a new tree.
But mention his law
and you've pulled your last straw!

Alternate version:
Ed Kapucinski
Every night, he plants a new tree.
He asks excitedly "Did you say Ménage à Trois?"
No, I said "Ed's Law."

It's a ghost engine. I can see the tender and it's white like a ghost, but the engine is completely transparent!

The T1 engine and tender finally reunited at the NSE convention in Milwaukee. Behind it builders Jason and Hans.

Wow! This thread is making me so heart-sick for a T1.  :?

It sounded like a good idea at the time... too bad the caboose wasn't in on the plan.
