Full restoration of an old Hobbytown E7
Posted by Darth Santa Fe on Sunday, February 14, 2021 12:52 AM

I picked this one up recently for an unusually low price.  The restoration took a couple weeks, most of which went to the decals.  I think it turned out pretty good, and that old Pittman DC-91 is a crazy powerful motor!

The video's pretty long this time.  I added some timestamps in the main description on YouTube.

Hey, Darth, another great project!  I followed this with interest since 2-3 years ago I bought hobbytown PA chassis to part out for axle gears and such. I posted it.  When other members here told me what I had acquired, with that massive 7 pole motor, I decided not to gut it, but make it a runner. I couldn't find a Hobbytown body. I used an Athearn. At least for now. I'd like a metal shell in SP Lark Gray and Scarlet colors.

I also found lightening up the carbon brush springs made it run easier and draw less current. I was surprised that such a HUGE motor could  draw well under half an amp. I eliminated all rubber tubing and went with U joints throughout, including undernieth. That eliminated some wobble. 

How do I "justify" a passenger loco on a freight only road?  The Model Railroader Cylopaeda of diesel Locomotives, noted that since Alco used it's bigger heavier traction motors on these, a number of them finished out their final years hauling freight. It'll earn it's keep!

Thanks for sharing another interesting video. Dan

PRR used multiple E units on Tructrains toward the end of their life but they NEVER painted one in an NYC paint scheme.  Sacralige!

I think the new paint scheme is a vast improvement over the original, Darth.  Now it has some class. Wink

Great video showing great work Darth!!!!

I bought an AB pair of Hobbytown E7s off eBay in 2015 to restore, $18 delivered for the pair.



The shells looked better than the frames.  A previous owner had removed the motors and drive lines.

I donated the frames to the County (Dump) and cleaned up the shells.



The shells dropped perfectly onto Athearn SD40-2 frames powered by Mabuchi 280 motors.



They weigh in at a bit over two pounds each and have tremendous drawbar, 16 ounces for the pair.

Thanks everyone!

Southgate 2, if you ever want a metal body, Hobbytown still has them available: Kit Catalog – hobbytown of Boston
It's the later design they acquired from Lindsay, so I don't know if it'll be quite the right fit for the original chassis, but it shouldn't be too much work to make it fit.

RR_Mel, nice looking set you have there! If you want truck sideframes to match, A Line used to make some to fit the SD45 trucks (they would need a little work to fit the SD40 trucks).  They're out of production, but you can still find them here and there.  I ran by this lot of 2 sets (8 sideframes total) just now: A-Line HO Scale #29300 E-Unit Sideframes (Fits Athearn Trucks) Lot of 2 NIP | eBay

I have 8 Athearn SD40-2 frames with E7 metal bodies, Cary and Hobbytown as well as a couple of Model Power.  I bought the side frames years ago while they were still in production.



The E7s are my favorite diesel.



Airbrushed using masking tape to form the deep V.

Great, then I guess you're all set on that!  I saw the SD40 frames in the photo and wasn't sure if you planned to change them out or not.Big Smile

Nice job on painting that V in the paint!  I have to do something similar soon for a CNJ Babyface, and that one doesn't have pinstripes to separate the colors, so extra care will definitely be needed to get it right.  I might do like I did with the bullet train and 3D print a cutting template to get the cut as clean as possible.

I did a drawing on my CAD then used it as a template for the masking tape.

Thanks for the link to the catalog, Darth. The price is less than I would have expected for metal.

My PA is still not as smooth I'd like it, I'll probably turn a great big ol flywheel for it and add power pickups to the dead sides of the trucks.

That catalog has some other useful goodies in it too.

Mel, i can see why those E units are your favorites. Nice!.

Kinda funny story about the E7s.  When I was growing up in the 40s a nabor kid had a Santa Fe War Bonnet Lionel and I had a Lionel 2-6-2 and I just hated his diesel.  I continued that way until I found out the SP had a bunch of E units so I bought an E7 off eBay and after I had done my thing in SP Daylight colors I was hooked.

The SP Cab Forwards and AC-9s are still my favorite locomotives but the E7 has a special place in my memories also.

I watched the video some more. I have plenty of respect for Pennsylvania RR, but that NYC scheme is just handsome, as if in top formal wear.

When working on a model this old, the model itself as a historic relic takes on more meaning than its accuracy as to little prototype details. It is the classic.
