Box cab loco info

Post by ccvstmr » Sat Nov 12, 2022 9:00 pm

Hi guys...looking for anybody out there in Chaski-land that owns a Cannonball 4-axle box cab. Need to sell off my Backyard Rails NYC F unit consist (A-A) because of storage space limitations. The consist has one powered and one dummy unit. Was wondering if the box cab loco satisfied your expectations? Did you get the extra 2-motor option? How does the loco perform with the extra pulling power? Looking forward to some responses. Thnx. Carl B.

I don't have a Cannonball box cab, but I have seen a few around from time to time. I can't speak to specifics about them, but they seem to have very similar performance to my West Valley electrics. I have seen one of the Box Cabs pulling a three car train with relative ease. I assume it has the 4 motor option. I know that I have seen a pair of Cannonball Little Macs hauling a few gondolas and rather large human freight at an impressive track speed. I think with the four motor option would would be happy with a box cab.

As a loose frame of reference, my electrics are pretty powerful. One can pull a two car train for about eight hours on a pair group 27 batteries. Depends on the load and grade of course, but they usually do pretty well for a days worth of running. However, I also keep a pair back up batteries in the caboose for reserve if I unexpectedly run low. This was a lesson I learned after buying batteries at Walmart.

Hi Garrett...

Would expect a 2 motor box cab to perform better...even with 4 or 5 cars on a track with 2.5% grades. Would only get better with a 4 motor version. Don't know what the Hp rating is for those motors. However, do know by comparison my 4'ish Hp rated Allen 10-wheeler will pull a 10-12 car train up that grades (no riders). That's approximately 1200 pounds on the tender drawbar. Still, would like to discuss loco performance with an owner...and then try to reach C-ball to determine availability.

Spare set of batteries? Good choice! Run on one set of batteries while the other batteries get charged...swap out batteries as need to keep going. Have seen that done many a time.

Thanks for the feedback. Carl B.

Carl,
The availability for Cannonball products was just discussed. Never hurts to follow up with Cannonball, but you may want to look at alternative options.

Thanks John...but my primary interest at this point is locomotive PERFORMANCE. Comments made in your referenced thread were about loco availability...more like a completed loco. Not interested in an R-T-R loco. Would rather build the loco myself...incorporating upgrades as I see fit along the way. As such, availability (at this point) was down on the list.

If the parts are available, no additional effort is needed on C-ball's part other than to box up the parts and ship 'em. If motors are a problem, THEN...that kinda kills the project.

Have sent a message to C-ball. At the least...and old expression come to mind..."the courtesy of a response would be appreciated". Carl B.

At home, one of my electrics easily handles a six car train with three or four riders. I have a short 4% and a short 5% grade. I can run for four or five hours no problem. But at a club track with longer runs, I try to keep the train length to a minimum so that I can put in the miles.

My son and I built a little 4 wheel electric critter, finishing it over the summer. it weighs about 250 lbs or just over that, and has two 350 watt 2750 RPM motors in it. It is geared for a theoretical top speed of 7.5 MPH. I have pulled a train that was approximately 1300 lbs weight around the Mid-South track with its 3%+ grades multiple times and didn't have a problem with it. It would lose speed down to about 6 MPH on the steep grades, but it pulled it well enough. If it slowed down much more than that, it would start slipping. That's a lot of train weight for such a small locomotive, definitely more than I had thought it would do during the design phase. I was extremely pleased with the performance of it.

Looking at the few specs that I can find on their website, Cannonball says that the Jackson and Sharp powered truck kit uses four 1/3 HP, 3000 RPM motors. I would assume that the powertrain in the boxcab uses the same motors and gearing. 1/3 HP is 250 watts, and that's about the minimum that I would want per axle for a 1 1/2" scale locomotive. Based just on that alone, because I can't find anything else at this point, I wouldn't go with the 2 motor version unless the motors were 500 watts each or you don't intend to do any heavy work with this locomotive, or it isn't going to weigh more than a couple of hundred pounds max.

Surely someone on here has one of these locomotives and can comment. I've seen one or two, and they seemed to perform well, but I don't know anything about them.

Pontiacguy...
That's the kind of info I was looking for. While you're loco might not be directly applicable to the C-ball box cab loco, your comments provided some basic background info that can be considered. Thank you. Carl B.

If you can find a mobility scooter or motorized wheel chair, you have just about all you need to power a box cab. My mobility scooter is powerful. If I run into a piece of furniture, it will push it aside. Look on E bay or craigs list for used scooters.

Ron, thanks for that tip. At this point, I'm not looking to re-engineer a scooter into a track mobile. But I can see where the idea of stripping down a scooter to re-purpose the electrical hardware might have some merit. Carl B.
