Here is a great animation of the PRR T1 4-4-4-4 #5550 running at speed. Animation done by Steve Hawirko
This is the running gear that we have chosen at it is most advanced, reliable and easiest to maintain.

I honestly cannot tell the difference between this animation and real life 😳

[@Farside2020]

You know, if you guys commissioned someone to do "5550 content" as donationware addons for games like Trainz, MTS, etc. you could probably raise funds for the completion of the locomotive, while also raising additional awareness for the project. I'm sure someone would be willing to work with the T1 Trust to that end, given folks are already making incredible animations like this. It might be worth a shot if you find yourselves falling short on funds or volunteers.

[@lucasquintanilla1673]

That was so good that it could’ve fooled me into thinking that the thing already existed if I didn’t know better. One of the many reasons I am excited by this project is that other than the fact that they will be making a streamline steam locomotive (of which there are sadly very little left in the United States) it’s also a long term Precedent, if this project succeeds then I would not be surprised if we will see other organized trusts form over the next several years to re-create other historic locomotives such as the Milwaukee Rd., Hiawatha and the New York Central mercury. That being said I don’t think we will see a full blown Hudson re-created for many decades to come since I think that we’ve still got quite a long ways to go until we get to that point.

[@Zero76606]

If you guys have the interior of the valve gear modelled yet, a video of that in operation would be fascinating. There's a lot of footage of more conventional valve gear in operation but this stuff is pretty novel.

[@overpoweredsteamproduction513]

This is what I’m really worried about, this was one of the main problems with the T1 originally, so I’m hoping they will fix it in some way

[@TheT1Trust]

There is nothing to be worried about. These running gear ran tens of thousands of miles every month with little maintance. The info you have is just not accurate.

[@Michael-eg3rs]

the "main problem" was none of the crews knowing how to operate the T1s. They were used to the K4's. Not the T1s. Another issue was the use of Poppet A instead of Poppet B which made them much better runners

[@BalticFilms144]

This is Franklin B type, not the Franklin A type which was the problematic valve gear. Engine 5500 was the only T1 to have the B type after a wreck and proved to run with no issues at all. There was going to be a conversion program for the T1s to be refitted but dieselization killed it.

[@holtzman1378]

ok it is the q2 but is cylinder horsepower the same as normal hp?

[@wizlish]

No. Cylinder horsepower is indicated using a formula like PLAN. The horsepower that 'matters' is drawbar horsepower or DBHP (although wheelrim horsepower is what was measured on the Altoona test plant).

[@xerenderstrongpaw2571]

Will 5550 have the porthole pilot or the running board pilot? Personally, I like the running board pilot the best on the T1.

[@Railfan105.]

I am curious, what is the purpose of the black piece that is connected to the driving rods that connects to a series of universal joints?

[@Kleman09]

Most likely part of an automatic lubricating system.

[@wizlish]

It is the right-angle gearbox for the rotary-cam poppet valve drive. Note that the eccentric crank is precisely centered, rather than leading or trailing as in radial gear: it gives precise rotational alignment past the rod circle.

[@Thelefevrefever]

Two Questions: First, will T1 have the skirting covering the front cylinders or not like in the video? Second, will the T1 have inside valve gear, outside valve gear, or the U-joint valve gear shown in the video?

[@TheT1Trust]

It will have the valve gear as you see it in video. It will be the "U-joint"

[@Thelefevrefever]

@@TheT1Trust Awesome! Good to know! Why did you choose this style of valve gear?

[@russellgxy2905]

@@Thelefevrefever Probably because this motion, Franklin B-2, it more accessible and reliable than the original Franklin A that the T1's were fitted with. 5500 actually had this gear after an accident, and was reported to be the best running of the T1's

[@daskriegsman7013]

A better question would be. How did your PC not turn into an atom bomb and rendering this vid?

[@TheRandomGamer692]

it even has the wheel slip in there

[@Thenormalnut]

will 5550 be equipped with an anti-wheel slip system? The original T-1s did not have them but the Q2s featured them and that apparently helped a lot.

[@russellgxy2905]

I don't think so. It's possible to start the T1's without slipping (or at least a violent slip) and considering the Trust will likely be testing the engine once it's done, they'll be better acquainted with it to avoid slipping. To me that was the main cause of the slipping with the T1's. Sure the front drivers had a bit less weight, but so do articulateds. Most crews were just too used to the hundreds of Pacifics to understand how to drive a Duplex properly, and with how quick the PRR started dieselizing there was even less reason to learn

[@wizlish]

The secret woe of the unconjugated duplex is that, if one driver loses traction, it reduces adhesion on the associated engine by 25%, not the 12.5% of an equivalent 4-8-4. The T1 has both the piston thrust and the high-cyclic valve efficiency to spin the engine until adhesion is restored, but on uncertain rail or bad cross-level one engine may slip repeatedly when operating at nearly full power on a suitable consist. Arresting these quickly without either cutting steam flow or binding the drivers is essential.

[@Phoenix308]

[@chooch1764]

Yes, much of the wheel slipping issues were already resolved with changes made to the spring rigging between the prototypes and production versions.

[@suekikun8888]

T1 i've got a question why you guys didn't try making the rods the same as the s1 6100 for you know respect the successor of the T1 and the s1 have somewhat have similarity to the T1 also try making the 5550 the second look the buick while you guys can change to the original looks like the 5541.

[@wizlish]

The Timken thin-section roller rods are a (great) improvement on the Big Engine arrangement.

[@suekikun8888]

@@wizlish Well i did say that because i saw one t1 that has the same rods as the 6100 yet i don't think that even existed

[@wizlish]

I don't think any T1 had the lightweight plain rods 6100 did (compare those rods with the ones on a Milwaukee A) If you look at 5547 as converted, you can clearly see the big rod eyes and thin sections of the Timken rods. Remember that the T1s had the shortest possible stroke that wouldn't weaken the web between the axle and main-pin fits, and even then the main pin was ground so the crank circle (and stroke) of the reciprocating main was just that little bit less. With ideal high-speed running gear... why go back to old-fashioned?

[@christopherallen1138]

Wait the T1 was a uniflow design?

[@wizlish]

No. A uniflow exhausts at the center of an elongated cylinder, with auxiliary valves if the simple port doesn't give adequate mass flow. The T1s have the Lentz arrangement (see Kirchoff's little 'coat of arms) with two admission and two exhaust valves in pairs at each end of each cylinder.

May happen, but this T1 will be better than the older T1s. The B2 Rotary Cam Poppet Valves are the solution to part of the wheel slipping issue. Also, Pennsylvania Railroad steam locomotive engineers didn't have proper training operating these locomotives, since transitioned from the K4.

[@NW-gi1cp]

[@wizlish]

Don't laugh: the NWHS has all the drawings to make the forging dies for the Timken lightweight roller rods (like the J's) applied to the last five locomotives built. With careful added guiding and compliance damping, that would make an A locomotive... fast enough.
