Re: Walthers lighted passenger cars

Hi Jerry:

I am building a large layout and have not had any problems with walthers passenger cars with lights (UP), going through blocks that are protected with NCE EB1 breakers.  I never seen a problem with lighted cars at the club layout I belong to.  You can go the web site and see if any information could be helpful.  "www.pacificsouthern.org"  I will ask some club members who understand electronics at a high level.

Regards,

Vince

Thank you, John, that is the information I need; we'll proceed on this basis.  He'll have to address his programming needs elsewise - finds JMRI too confusing.

Yes, JMRI can handle, but you would have to connect to JMRI separately and with the DCS50 as a command station.

 

Connect a LocoNet cable from the interface to the computer to the DCS50 and set the JMRI preferences for the DCS50. Then you can set the OpSws, setting the OpSw #2 = “c” last. Once you set the DCS50 to be a Booster you cannot then change other parameters.

Thanks, John.  I won't put another booster on the Christmas list, then.  Thanks, also, for those opsw pointers.

Would you know if JMRI could be used to manage this config?  I'd like to have as many devices as possible all under one roof, accessed through the throttle network.

Hi Blair:

Yes, you can do what you suggest.

The DCS50 does function well as a 2.5 Amp Booster; set OpSw #2 = "c". Yes, you can still use the throttle on the DCS50.

For interfacing with a PM42 you can set the DCS50 to 1/2 second shutdown so the PM42 will trip first; set OpSw #18 = "c".

When set as a Booster the programming function of the DCS50 is turned off.

Hope this helps.

Hi

- can the built in throttle still be used on the loconet network, for example as a yard throttle?
- are there any things to beware of when doing this?  (i.e. is there a trip speed issue, or other limitation, between the PM42 and the DCS50?) I see nothing useful in the Digitrax literature.

Re: PECO Code 100 24 Degree Crossing: Shorting Issue

Hi Dan, I use the TAM Valley dual frog juicer on my PECO crossing. Works like a champ. They have great products. I have many various juicers installed under my layout. See you Saturday.

Re: PECO Code 100 24 Degree Crossing: Shorting Issue

I had the same issue. I believe I set OP switch 18 to C (closed) on my DCS51 to extend the short recognition time. It seems to have done the trick. BTW if you reset the DCS51 or command station back to factory defaults OP switch 39 to C you will have to do this again etc.

Re: Walthers lighted passenger cars

Don Vollrath
 

Jerry you have rediscovered the reason to make all AR sections longer than the longest train. Many passenger cars have multi-axle pickup where two or more axes on a Truck are electrically connected together even if the power pickup is not being used. As a result the multi-axle truck acts like a Long jumper across each isolating gap In the rails. This causes confusion and even short circuits to the AR controller when a loco or other multi-axle pick up truck also happens to be crossing an isolating gap at the other end of the AR section. I don’t see any way adding diodes will resolve the issue.
Fixes. ... adjust the length of the AR section slightly to avoid simultaneous crossing of the gaps at both ends of the AR section using your particular train car lengths.
Be sure to fill AR section gaps so that steel wheels cannot fall into the gap while touching both rails.
Avoid using wires inside the car to achieve multi-truck pickup to reduce light blinking. (Use some other electrical technique)
If you are not using car lighting use plastic wheels to avoid bridging the gaps.

Re: Walthers lighted passenger cars

Hello Jerry:

Thanks for the additional information:

So one option would be to power the lights from just one truck. You would still need the "dead" section.

If you want to avoid flickers and have power over the gap you could add 8 diodes, four for each truck. Lets just assume LED lights so we know the current can only flow one way. So the wheels on each side would be routed to two diodes. These diodes would be routed to the appropriate side of the LED lights. The diodes only need to be large enough to carry the LED lights.

Re: Walthers lighted passenger cars

Hello Chuck:

Thanks for the information.

If you could make the reversing section longer than your longest train would be best, but I figure you have a limit to keep.

Here are my suggestions:

1) Insulate the trucks from the car frame, if not already.

2) Cut in a short block at each end of the reversing block, a bit larger than the passenger trucks. Just let this be dead track, 8cm perhaps.

Your locomotives should be able to bridge these new blocks, and still allow enough space for the passenger trucks to cross with out shorting.

The other option is to insulate all the passenger car wheels. I know metal wheels roll better, could you switch to plastic side frames? Or perhaps insulate the axles from both wheels.

What you don't want is the wheels connecting the rails at the gap when the current is reversed.

Hope this helps.

Carl.

Re: Walthers lighted passenger cars

Hello Chuck:

A small diode should do, it just needs to carry the current of the lights in the car.

For the rest I'll need some more details.

Are we talking 2 rail HO? Are the trucks picking up power from one rail, or both?

Is the passenger train long enough to reach 3 blocks, or from the first, across the second block and back to the first?

Are the blocks at the same "polarity"?

Thanks, Carl.

Re: Walthers lighted passenger cars

Hello:

May I suggest a pair of diodes, one to each truck so the power can't flow from one block to the other.

I had a similar problem with my K-Line passenger car. I was using a ZW to power two blocks and had parked the passenger car across the gap. The ZW has no over current protection between the power taps. The high voltage burned all the insulation off the roller wires.

Our layout has been operating quite well recently, with the phase problems solved and not repeating for a couple of months.  However, we recently started testing a few passenger trains, and we are running into a curious problem with lighted Walthers passenger cars.

Although a string of up to four locomotives pass from one block to another with ease as they straddle two independent blocks, even those junctures crossing blocks powered by different boosters, the Walthers lighted passenger cars short out the blocks.  When we insulate one set of trucks (putting tape across the contacts), the problem goes away, but then we get flickering lights across the blocks.

Re: Book on DCC wiring

wirefordcc
 

Thanks for the kind words, Jerry!

I had offered the website as PDF files, but the Supreme Court's decision that I would have to collect sales tax for every state that I shipped to made continuing this service impractical. 

All is not lost. I do intend to create an eBook that I would sell through services that currently offer eBooks (like Amazon) and let them collect the sales tax.  I just can't say when I will complete this.  My website is about 600 printed pages - more than any current DCC book that I am aware of - so I have a huge project ahead of me.

I have software that will create PDF's with hyperlinks.  So you will have the advantage of having my eBook on your computer and being able to jump around the book like you can do on a web page.

Stay tuned!  I'll announce the book here on the Q&A forum.  Stay tuned, just don't hold your breath waiting! :)
