Do the DLPRR locos have crosshead pumps on the engineer's side?

In the pictures I've seen of the Paris locos, they each seem to have a crosshead pump on the engineer's side of the locomotive, behind the runnig gear. (drive rod) Also, the pump seems to be connected to the large check valve on the boiler, is this so?

This is just something I'd like to confirm since I am planning a kitbashing project on a G scale locomotive and will make it resemble the C.K. Holliday. Also, because my model will be a 2-6-0 mogul and not a 4-4-0, would an inside-running-gear crosshead pump look accurate on a mogul?

Yes, that is (or at least appears to be) a crosshead pump.



Are you also going to model the backwards-facing cab hatch?

The moguls with crosshead pumps pictured in John White's book show them outside of the crosshead guides. For those engines, the rear end of the crosshead guides are in front of the trailing edge of the front driver.

Well...not all of them. See page 488 of his book "American Locomotives."

That's definetly a crosshead pump; I wonder if they are actually fuctional too like the ones at WDW. The crosshead pumps on all four of the Paris locos appear to be of the same style as well.

No the one on my model will be facing foward and kept shut too as it is an engine that would rather be pictured in a cold climate. I did notice that on the Eureka sometime ago, it does look a little odd to me but then again the Paris locos have unique features that I find to be refreshing. The other three locomotives have their cab roof hatches facing foward.

So if there have been moguls with their crosshead pumps inside the running gear, I suppose I can decide on which way will look better on my model. It will probably be inside too because I want it to be connected to the check valve like on the real thing.

Also, if you notice, they have oversized brake pumps that go through the running boards. While this might look great on a 4-4-0, how accurate would it look on a mogul? I like to think of my model as somewhat of a mogul version of the C.K.

The reason I said they "appear" to be croshead pumps is because they may only be decorative, and non-functional.

Whether mounted inside or outside, they will always be connected to a check valve.

The prime reason for determining pump mounting location simply has to do with where the pump would fit best.


Compressor location has nothing to do with "accuracy." Steam locomotives are very much a form-follows-function machine. Appliances are mounted wherever is most efficient.

That pretty much answers all my questions. Because I'm kitbashing, looks is the biggest thing I'm taking into account, that includes accuracy in appearing functional as well.

If you are unsure of the way pipes or other appliances are supposed to be placed, you can just post pictures or ask your questions here. There are several steam experts on this site that can answer them.

Since you're free-lancing, you have wide latitude on how you do things. The compressor, for example: Disneyland's 4-4-0s have them placed with the top, steam portion above the running board, with the "air" side below. On the WDW RR, the entire compressor is mounted above the running board.

Thanks Steve, I'm pretty familiar with how and where appliances and other components should go. I'm just brainstorming and sharing thoughts to have other's opinions because like you said, this is free-lance and I have many options. I've already done one kitbashing project of this type and was very satisfied with the results. However that project wasn't a free-lance because it was the Walter E. Disney that I modeled not based on. But the two projects I'm doing now are based on the Paris C.K. and Roger E. Broggie so I can add more personal touches. For example, I gave the engine based on Roger a drawbar and a larger cowcatcher and pilot deck than the prototype. And each engine has their own whistle that sound just like the prototypes. (They are air whistles)

Denver Express, Do the locomotives you're starting with have electric or battery mechanisms? And are you changing them in some way?
