First, I want to point out that the Steamtown NPS website says that B&M #3713 will be replacing CN #3254 as the site's mainline locomotive power. Whether that means indefinately or for the time being I'm not sure.
Reasons the NKP #759 and Reading #2124 probably won't be restored to operation and why R&N #425 would not go on loan to Steamtown:
Reading T-1 (Northern) #2124
1. The Reading T-1 #2102 is already being restored. Steamtown wouldn't benefit as much from having the exact engine another group is already restoring.
2. There are already many 'Northern' type locomotives in operation.
3. It would not fit on the Steamtown turntable.
4. It would not fit in the Steamtown roundhouse (if it does there would be almost no room for error in parking it).
NKP Berkshire #759
1. There is already an NKP Berkshire (#765) in operation. Steamtown wouldn't benefit as much from having the exact engine another group is already operating.
2. It doesn't fit on the Steamtown turntable unless the gates stopping people from falling in the TT pit are removed.
3. Even though the engine is in really good shape the logistics of returning the #759 to operation at Steamtown will prevent it from happening.
3a. I could see Steamtown trading the #759 to someone for a locomotive to restore to opeating condition if they could "get over" the historical value of the engine (it's life with the HICO and pulling the American Freedom Train). Right now its hard to appreciate the size of the engine when it just sits in the roundhouse. But, it's in such good condition they could never put it outside (and rightly so). I am one of the last people who would want to see this engine leave steamtown but at the same time I do consider this a possibility.
Reading and Northern #425
1. The Steamtown NPS website says after the BLW #26 0-6-0 switcher is up and running the next two locomotives to be restored to operation will be B&M #3713 and CP #2317 both of which are 4-6-2 Pacific type locomotives; just like #425. Steamtown probably wouldn't want three Pacifics and an 0-6-0 as part of their locomotive roster. They would much rather have a more varied roster.
2. R&N would probably like to have their locomotive available for their own use.
My best 3 guesses for the future of steamtown in terms of a "4th locomotive":
1. Steamtown restores a locomotive they currently own.
- Here is a list of possible locomotive choices for restoration to operation (all owned by Steamtown) and their tractive efforts (#3713 and #3254 listed for comparison)
B&M #3713 (4-6-2 Pacific) - Tractive Effort: 40,900 lbf
CN #3254 (2-8-2 Mikado) - Tractive Effort: 53,115 lbf
a. Grand Trunk and Western #6039 (4-8-2 Mountain) - Tractive Effort: 49,590 lbf
b. Illinois Central #790 (2-8-0 Consolidation) - Tractive Effort: 42,000 lbf
c. Maine Central #519 (2-8-0 Consolidation) - Tractive Effort: 37,000 lbf
d. Rahway Valley #15 (2-8-0 Consolidation) - Tractive Effort: 35,360 lbf
- I think the one with the highest chance of restoration are GT&W #6039. It has the tractive effort to pull the 7 car trains up the Pocono main. I am fairly certain that it will fit on the TT but I'm not 100% sure. I know if it does it's pretty close. The Vanderbilt tender makes it unique, something Steamtown can benefit from. The only problem (other than the possible TT issue) I have read is that there may be some cylinder scarring which would be a big problem to overcome in restoration.
2. Something happens with NKP #759
- Either they sell/trade it for another locomotive or they restore #759 themselves.
3. Steamtown restores CN #3254 with all of her flaws no matter how long it takes or how hard it will be.
Closing Notes: I just spent way to much time on this to post to something that's been dead for a year.
