Cool Calculator !! But... I entered 2 inches at 8 seconds ( 1 inch at 4 seconds) and it shows scale speed at 2.27 Mph. Am I doing something wrong?:tb-wacky:
uh.. check my math, but I am coming up with 2.27 mph to travel 2" in 8 seconds, which would be the same as 4 seconds and 1" correct?
I guess those numbers are wrong. I just entered incorrect data. Calculator is the important thing. You get the idea. Yes. That's what I get.
Either way...this DDC is 'Da-Bomb' !! Awesome control...awesome speed adjustments. (See my other post on DCC Rules...LOL .
I have a model tramway in OO/HO. It's in storage awaiting my time to rebuild it, but it has to comply with the 30mph restriction here: six inches in one second (say it slowly as one thousand and one) is 30mph. It should be an easy conversion into N from that. 2.27 mph is well adrift, I'd say. 22.7 maybe! Regards, Pete
Pete: To convert your time/distance to the actual N scale time/distance: Six inches for the N scale engine would take 24 seconds. Your 30 scale mph in H0 scale is correct as is the 2.27 scale mph in N scale also correct. My two cents.

Too bad there is no way to upload files to this site. I have an Excel spreadsheet that has a speed table for scale speed from 0 to 200 miles per hour. Just divide the distance by the time and you just look up the speed. It is only in round numbers of mph. I use it for a quick reference of sorts. In the above example, 1 inch in 4 seconds = 0.25 In the spreadsheet, 0.24 equals 2 scale miles per hour, so just a little over 2 smph is correct. The spreadsheet can be used for any scale.
