I use a circle for my test track. Most every one has some sort of circle of somesort of snap track etc.

Dana, thanks for these clear, concise, informative and interesting videos! You are a good teacher and I look forward to what eles you have in store. I’m a newb to DCC and look forward to other videos. I use the Zephyr xtra command station and would like to see you use this as well.

Also, post some reference notes for us to refer to.

Thanks

Great series. Good job Dana. Looking forward to more installments.

Dana: Great job. I appreciate more advanced technical videos.

Thanks Dana! Very enlightening. I didn’t know that Marklin speedometer existed. A Canadian company, Bachrus, has one too.

Very interesting and instructive, thank you Dana!

Great exploration of a somewhat mysterious topic; glad to see “advanced” content here.

Helpful. looking forward to the next part.

There is an iphone ap: ModelSpeed that can make scale speed measurement easier than using a stop watch.

Thank Dana, nice video. I’m starting to understand the process. The Digitraxx Zephyr uses a throttle control that is more like a traditional rheostat, so I can’t set a “Speed Step” - do you just move the knob to the same position for each loco? Thanks

This topic really confuses me. If your protypically modeling then first and second generation diesels were always loading at different rates. For example, if you had an SD40-2 and a B30-7, the GE unit would load as soon as the throttle was moved and the independent brake was released there-by running into the SD40-2. It’s a lot less noticable at higher throttle settings and speeds.
Todays unit’s, with their computer software, have nuetralized all the bumping.

Very interesting and informative video. Thanks, Dana.

Instead of trying to speed match 2 locos I have measured a section of track on the layout and I know that for a 35 smph it’s suppose to take 25 seconds and at 70 smph it’s suppose to take 12.5 seconds . This way all my locos are matched . Don’t forget that if a loco has not been used for a period of time at first it will be much slower than the programmation , after a while it will be back to what it’s supposed to be .

BTW I am using CV3 and CV4 for momentum acceleration and decelaration . I am using CV6 to adjust the midspeed and CV5 for top speed .

Great video Dana , i’ll be looking for the next one using the speed tables .

Hi Gary,
Yes with the Zephyr you can just move the throttle to the same position.

Good Video Dana! Where may I obtain the Markli’n digital speedometer you used in this video. I can’t find it.

Hello William,
I don’t think Marklin makes the speedometer any more. However, there are several manufacturers who currently make model railroad speedometers. I’d suggest you check out Bachrus at http://www.bachrus.com/speedometer.php
We reviewed the firm’s speedometer in the April 2010 issue, which you can read online at ModelRailroader.com.

Dana,
I’ve enjoyed this series immensely, I often recommend it to friends who have or are thinking about buying DCC. Sadly many of them are not MVP subscribers but are MR subscribers, any chance of this series being run on the magazine site? Keep up the good work, I’m looking forward to the next installment!!
