1  Discussion Boards / HO / Re: Do other companies locomotives run with Bachmann Controllers? on: February 16, 2018, 10:55:45 PM
You should be able to run any locomotive equipped with a DCC decoder. If your Kato is not equipped you'll have to convert it yourself. Most of the time it is as simple as plugging a decoder into a socket, but not always.

what you are doing with an on off switch  to control power to a section of track is a time tested concept that was used for many years before DCC came along. It is known as block control. Using only one rail to control the section via a single pole switch is also time tested, known as common rail wiring, where one rail acts as a common return to the power supply, similar to a grounded chassis in electronic equipment. Unless you have a special situation such as a reversing loop, there is no need to isolate both rails, or use a double pole switch. In your case, where you are merely killing power to a section of track, a SPST, or on-off switch will do just fine. Just be sure that the contacts can handle the current output of your power supply. In the case of EZ command, with a 1 amp output, a switch you can buy in Radio Shack with contacts rated 3 amps will be more than enough.

The concept here can also be applied as many times as you want on your layout. You could, for example, have every siding on your layout isolated, and park all your locomotives in their own track when not in use.

the switch control boxes should be designed so they gang together. a single cable from the accessory terminals on the controller to the boxes will power them all. You are only going to be throwing one switch at a time so it doesn't matter how many boxes are in the string.

Using the 14 piece pier set, each pier under a track joint for optimal support, gives a grade of just under 5%. Even a heavy diesel would have trouble pulling more than 3 or 4 cars up that. I have a stretch of 4@ on my own layout, and those numbers are based on my experience. Figures listed in an old Atlas layout plan book indicate that pulling power is reduced to 1/6 on a 4% grade, compared to what it will pull on level track.

Using two pier sets, with shims as Len suggested, will still yield a grade of about 2.5%. That is much better, but will still significantly reduce your locomotive's ability to pull a train up the grade. Ironically, the track configuration you are considering, using the pieces described by bbmiroku, would give a grade of about 3% if the rise and fall were evenly distributed around the track.

To use the two pier sets as described by Len requires a 4 additional straight pieces, two on each side of the figure 8. The two straight pieces can be located anywhere on the curve, but must be directly across from each other. If you experiment with their location, you should be able to fit the enlarges figure 8 on a 4x8 sheet of plywood.

MY system is digitrax, and I can easily call up any locomotive by entering its number as the address. My dad has MRC, and a friend has NCE, and on both systems calling up a locomotive is similar. Wonder why you can't do that on Dynamis?

Hunt would be the best person to answer your question. He is the go to guy for this system.

Just wondering why you didn't use the locomotive number as the address? That way you'd just enter the locomotive number to control it. The only thing you'd have to remember is what numbers you assigned to your consists. And you should be able to enter those directly as well. Direct entry of addresses is the way most dcc systems handle this problem.

Are you sure you know how grade percentages are calculated? 1% is 1 inch rise per 100 inches of track. You can NOT get a 1% grade using a pier set. 1% would require at least 300" of run. That's 25 feet, or about 34 track sections. The track rise per section would be about 3/32". Using 7 piers over 25 feet would leave then over 3 feet apart, providing NO support for the track. Added to that, the room required for such a gentle grade would make it impractical to use in most situations.

Before you buy anything, remember this:

The General is a small locomotive that doesn't have a lot of pulling power. Upgrades severely reduce that pulling power. With the steep incline of the pier set, you may find that your locomotive will only pull itself, or at most one or two cars up the grade. You'd be better off using this one on level track.

If you do want an over and under configuration, the best thing you can do is lengthen the length of the upgrade, thus reducing its steepness. I would suggest that, instead of using a pier set that you look into the incline sets from Woodland Scenics. They come in 2%, 3% and 4% inclines, and I would suggest using the 2% set if you can. The lower the grade the more cars you'll be able to pull.

do they have one that smells like coal smoke?

I have converted these 0-6-0s to dcc. There isn't a lot of room, so I removed the smoke unit and used that space to hold a Z scale decoder.

You mentioned VAC, which means volts-AC. Did you accidentally connect the track to the AC terminals of your power supply instead of the dc? That could have catastrophic effects on a DC locomotive.
12  Discussion Boards / HO / Re: Passenger Car Minimum Radius? on: January 14, 2018, 10:38:26 PM
I'd say 24r or greater.

Got so many i'm not even sure what I have anymore.

Don't y'all think that the argument over what to call those cars has detracted from the posts that actually HELP the guy?

Power routing may not be a good idea with dcc. On a power routing switch, both points and frog are the same polarity as the rail that one of the points is in contact with. That leaves a situation where the wheel backs may brush a point of opposite polarity, causing a momentary short. This is not noticeable on DC, but on DCC it may instantaneously shut down your command station.

I learned this lesson the hard way when I first started using dcc with my handlaid switches, which were easier to build as power routing types. I had to modify my construction methods to eliminate the problem.

Much better with DCC to use an isolated section with an on-off switch (spst) to kill the power.
