ATSF 1656. A Westside story of a labor of love.

Engineers side of 1656.

As far as brass engines go, 1656 is not the rarest piece I have, nor is it the most expensive, nor the first I ever bought. It does however hold a bit of sentimentality for me, I loved the turtleback tender and general looks of the engine. However it also is a love and hate piece because of the year plus of "fun" I had with this engine to get it running well. 

Purchased in the early summer of 2015 while I was still a courtesy clerk, this model is a Westside 3010 Class engine produced in the 70's. Came in the red-white-and-blue circus box with a belt buckle stamped 3010 class of all things. It wasn't my first ever brass engine, Balboa Atlantic #1432 takes that for the record, but this was the first brass engine I ever bought solely on my own income without any assistance from birthday money.

I opened the box with great excitement when the engine showed up. Yes, it had some flaws in it's brass finish, but outside of that I thought it looked great.

So I had plans for 1656 when it was delivered. I knew I wasn't going to keep the 3010 class, being as that was only 10 engines. I found the Santa Fe Historical Society had some online info on the turtleback tenders including a listing of all the engines that had the turtlebacks at one point or another. There were 1800 class prairies in there, however there also were 1600 class 2-10-2's that got these tenders at some point. 

A little history, the Santa Fe only had 10 of these turtleback tenders, and they were for the 3000 class 2-10-10-2's built in the 1910's. The engines were used as helpers among other things and the sloped back tenders were to help with backing visibility. They even had pilots on the tenders for some of their lives. Towards the middle of the decade the Santa Fe decided the 2-10-10-2's were not worth the extra upkeep and they split them, becoming 2 2-10-2's each. One section became the 3010 class, the other became the 3020 class. These engines were virtually the same as the already on the road 1600 and 900 class 2-10-2's. 

Using that roster I mentioned above, I decided to go for #1656, which did carry around a turtleback at some point in it's career. 

The model itself came with a KTM open frame motor that actually ran pretty good on my test track at home and didn't draw all that many amps, running an average of a 1/4 amp or less. I planned on keeping this motor and just installing a decoder with it since the motor was isolated. Later that week it received a digitrax DZ125 from the spares pile and it went down to the club for testing. 

While at home on the test track, performance was good, I found at the club performance was less than stellar. This was a problem that would only get worse and wouldn't be solved for over a year.  It did run decent enough I figured I would try to run it during our July open house for the organ society. Boy, did it have other plans though. After running during the open house what was probably a collective 12 feet, the engine came to an abrupt haul, with some smoke rolling out of the cab. After putting it away for the remainder of the show, a later check revealed it was the decoder that let out the smoke, with a nice scorch mark on the red plastic, and a small hole through the PC board. The decoder surprisingly still worked, and resides in service, in my switcher FT #405L to this day. 

While the decoder was smoked, it didn't seem like anything caused the motor to stall out, not that it's really possible. Even under a stall load the motor was within the limits of the decoder. At that point I ordered a canon DN-22 motor off ebay to remotor the engine with. Little did I know how much fun it was going to be.

The DN22 showed up not too long later. It wasn't my first run at the rodeo, I had remotored my Balboa 4-4-2 not too long before that, and a United-PFM 2-8-0 on my desk was also due to get a remotoring (also with a DN22). So I set about to install the motor the same way as normal, the installation itself went pretty well, no snags here, and since it had an open cab with no backhead like the atlantic and the consolidation, it took much less time. 

So back on the tracks it goes...... With less than stellar results, the DN-22's I had bought were extremely low RPM motors, 1656 could only make 30smph at full power. While not un-prototypical for the engine, I do operate on a mainline with other people, so to spare them the agony of following me, the motor had to go. It would be quite some time before a replacement would pop up though. 

New front coupler on 1656.
Per instructions from Jason Hill over at Owl Mountain Models who's blog you can find here, I installed a front coupler on 1656. It's a long center shank scale kadee whisker coupler thats had it's hoop on the end cut off and filed down. A small hole was drilled to allow the little wire that held the dummy coupler on the engine to also hold this coupler. It's worked great for me, and I got to keep the details on the front instead of hacking out for a kadee box. 

The first thing 1656 needed after this was paint. So out came the normal rattle can of rustoleum automotive black primer. I'd painted my 2-8-0 this way, and it dries a great flat color.

1656 rolled out of the paint shop after coat #1 looking quite spiffy. However I had to deal with the old school modeling moans of "you need to bake the paint to get it to set right on brass!" after I showed off coat one. So I bit the bullet and elected to try this. I removed everything* I though was plastic from the model, and hit it with a heat gun while applying the paint. This did absolutely nothing to the paint. So I elected to just live with how it turned out without the heat. I reassembled the model, put it on the desk and went to roll it back and forth, however the drivers were locked up tight. 

Remember the "everything* plastic" from before? Well, I had missed one thing, and it was a rather critical piece for the drive to function. 

one slightly melty gear
There was one thing I missed when hitting the model with heat, and that was the idler gear in the gearbox was plastic. It of course melted on some of the teeth on the bottom, rendering it useless as a gear. I ordered a new KTM gearbox from the local brass guy, installed it, and carried on my way like nothing had happened. 

Tender with a new pilot.
I installed a precision scale pilot on the rear not too long later, I think the tender looks much cooler with it installed. I made sure I could still get a slightly modified kadee #5 box in there after the pilot went on, I actually operate my engines, they don't sit on display shelves. 

Now we're going to get the long part without many photos, 1656 and I had a very rough year following. 

The tender pilot got installed in September of 2015 just in time for the local TECO show. I bought 1656 to the show, ready to show off the tender that everyone oogled over where ever it went. I had tested the engine at both the club and at home, it's performance could have been put as mediocre but it ran OK. During TECO 2015 I proceeded to be very embarrassed when 1656 hobbled down the track for a very short distance before shorting out on something. A quick touch up of clear nail polish to cover the spot where the engine touched the tender took care of the shorting issue. However after another lap it spun the driveshaft inside and was dead in the water again. It did not see track time during the show after this. 

I dabbled with 1656 trying to work out its problems for the next few months until December of 2015. That was a big month for model railroading in the area, we had several open houses at the pikemasters and the TCA show in Denver was also that month. I didn't run 1656 during the first pikemasters show, but I did take it to TCA expecting to atleast run it a little bit. However the engine was un-cooperative and spent the show on the sideline with a small bind in the drive. 

A few weeks later at the Pikemasters open house I tried to run 1656 again, without much luck. More binds in the drive interfering with operation. It seemed as I would chase the binds through the drive, more would show up on the other side (front to back) of the engine. This continued as a "trend" for the engine until the March 2016 TCA show when it once again, was un-serviceable due to a bind. Having gotten frustrated with the engine, it went on the shelf and sat there for several months.

During these few months we were meeting at a local member's house rather than the club due to the renovations they were doing at the city auditorium, I bought 1656 to his layout on a night in June. We tried to to run it, to much the same problems it always had, a bind that would make the shaft slip off the motor. Once again frustrated I was about to pack it up and was even contemplating on selling the engine. When I was about to pick it up, I noticed something odd about how the engine was sitting. the center driver didn't touch the rail, but in fact was being held in the air. Something I had never noticed before. 

Back at the shops, I examined the engine and realized the center driver was locked in an upright position, with the rods all sloping down to the end drivers. The bottom plate that retained the drivers was warped, and since the screws aren't at the ends, It forced the center driver hard up, and let the end drivers flop around to the point where their springs were all the way out. I pulled off the plate, and straightened it out on a flat table with a hammer. After reinstalling the plate, with the gearbox out, I pushed the engine, and it rolled down the table like glass. 

A year into the frustration of this engine, and the entire problem lay with a warped plate on the bottom of the engine. A few more tweaks to "undo" the modifications I had made to prevent the binds with the drooping drivers and it rolled even better. I re-installed the gearbox, threw the canon motor on it, and let it roll on the stand, it worked GREAT. 

I decided at that time to replace the burnt DZ125 and the canon DN22. Replacing those were a different canon motor out of a Stewart model and a ESU Lokpilot decoder. I also installed both an LED headlight and backup light. The firebox also got a yellow LED to provide a flickering effect from the bottom. I also received some actual graphite paint used in the restoration of C&S 60 and painted my smokebox with it. It dries with a textured look and looks great in person.

During a later run at the Denver County Fair in August of 2016, 1656 ran at the show like a champ. After a year of bashing my head against the wall, it finally ran like I wanted it to. 

Now 1656 isn't perfect by any means, all the handling of the engine while trying to fix binds has resulted in a bunch of the paint flaking off in places, and the massive plug for the tender lights has got to go. During all this the handbrake wheel for the tender has come off, and my numbers on the numberboards have disappeared. However, I will take all these things for an engine that runs as good as it does now.

Tender decals and paint could use a touchup.  

So there we have it, a story about a year long of trial and error, and of many headaches and cursing. However in the end, I have a model I can really be proud of. Some detail work and some touch ups and it will look as good as it finally runs.
