Can you just get the part and repair it your self?

All railroads used class numbers or letters.  Like the Santa Fe had say 200 mikes 2-8-2 with 6 or more classes.

Did one of the tender trucks get turn around?

The reason no more were built was the fact that the K4 was a better locomotive.  One big mistake Penn RR made was not using NW J"s blueprints and made 4-8-4s instead of the T1s.  The J's were a much better locomotive then the T1s at a lower cost.  Any way that is the way I see it.

The Pennsylvania Railroad's class K5 was an experimental 4-6-2 "Pacific" type, built in 1929 to see if a larger Pacific than the standard K4s was worthwhile. Two prototypes were built, #5698 at the PRR's own Altoona Works, and #5699 by the Baldwin Locomotive Works. Although classified identically, the two locomotives differed in many aspects, as detailed below. They were both fitted with a much fatter boiler than the K4s, but dimensionally similar to those of the I1s 2-10-0 "Decapods". Most other dimensions were enlarged over the K4s as well; the exceptions being the 70 square feet (6.5 m2) grate area and the 80 in (2.032 m) drivers.

In comparison:
   K4s    K5
Cylinders    27 in 28 in (686 mm 711 mm)    27 in 30 in (686 mm 762 mm))
Boiler pressure    205 psi (1.41 MPa)    250 psi (1.7 MPa)
Total heating surface    4,041 square feet (375.4 m2)    4,285 square feet (398.1 m2)
Superheating surface    943 square feet (87.6 m2)    1,634 square feet (151.8 m2)
Weight on drivers    201,830 pounds (91,550 kg)    208,250 pounds (94,460 kg)
Total weight    308,890 pounds (140,110 kg)    327,560 pounds (148,580 kg)
Tractive effort    44,460 lbf (197.8 kN)    54,675 lbf (243.21 kN)
Factor of adhesion    4.54    3.80

The K5's factor of adhesion was much worse than the K4s'. This is because the K5 was more powerful than the K4s but with little more weight on drivers (and thus adhesion). Factors of adhesion below 4 are often considered undesirable for steam locomotives, and the K5 design did prove to be rather less sure-footed because of it. For this reason, 4-8-2 "Mountain" and 4-8-4 "Northern" designs with more drivers (and thus a greater allowable weight on drivers within the same axle load limit) were generally considered preferable for locomotives as powerful as the K5.

Both K5 locomotives were given a 130-P-75 tender carrying 12,475 US gal (47,220 L; 10,388 imp gal) of water and 22 short tons (20.0 t; 19.6 long tons) of coal. Surprisingly for such large locomotives built at such a late date, both were equipped for hand firing. Both were fitted with Worthington-pattern feedwater heaters, power reverse, unflanged main drivers, and both used nickel steel boiler shells. As built, both carried their bell on the smokebox front, hung below the headlight; this arrangement was common on other roads but at the time unique on the PRR.

The question is why do you need it?
39  Discussion Boards / HO / Re: Faster in reverse? on: June 04, 2017, 07:20:58 PM
I know the locomotive does not have a transmission, but it has gears.  You can have more friction one direction than you do in the other.  If you have more friction it is going to cause it to run slower.

No I think it has more to do with the gears then the motor.  What locomotive is it?
41  Discussion Boards / HO / Re: Power taps? on: June 03, 2017, 08:14:13 PM
my thinking is on flex track to solder rail & jumper every 6 foot.  That way you would never be more than 3 feet from a jumper.   
42  Discussion Boards / General Discussion / Re: Can someone identify where this is? on: May 31, 2017, 06:59:32 PM
If you are rail fanning to St Louis, it is a must see.  Look them up on the web.

We don't need to be like face book.  Lets just keep the board simple and neat.  I hope every one remembered those that gave their all so we would have freedom.

I think you would be OK.

I guess we will never know who Bob is.
