    Does anyone have a chart for scale speeds? I'm looking for something that goes up in 5 MPH incriments. It would be good if it were only about 2 or 3 feet long also, so you could measure your speed often and quickly. Thanks in advance!

    Here is a quick one.


    Speed Inches per second
    MPH = N - HO
    1 = 0.11 - 0.2
    2 = 0.22 - 0.4
    5 = 0.55 - 1.01
    10 = 1.10 - 2.02
    15 = 1.65 - 3.03
    20 = 2.20 - 4.04
    25 = 2.75 - 5.05
    30 = 3.30 - 6.06
    35 = 3.85 - 7.07
    40 = 4.40 - 8.08
    45 = 4.95 - 9.09
    50 = 5.50 - 10.1
    55 = 6.05 - 11.1
    60 = 6.60 - 12.1
    70 = 7.70 - 14.1
    80 = 8.80 - 16.2
    90 = 9.90 - 18.2
    100 = 11.0 - 20.2
    110 = 12.1 - 22.2
    120 = 13.2 - 24.2
    150 = 16.5 - 30.3

    Mike, divide the feet traveled by the seconds it took and multiply by 109. I.E. four foot of module in 5 seconds = .8 times 109 = 87.2 scale miles per hour.

    Mike going to see if I can attach a chart I made up for our clubs next show. Give the children something to do other than ask "is that as fast as that train will go?"

    That's exactly what I needed Sandro, thanks! I went down and calculated that I've got all my engines set so maximum on the Digitrax throttle is 40 MPH. I usually say that 85 is the fastest you can go, which is about 35MPH. It's right where I wanted it, since the maximum speed on the real Laggan Sub is 40MPH. Thanks again Sandro.

    Guys, I saw a scale model train speedometer that works for any scale at the last GSMTS. Check out the following website. www.trainspeed.com. This item appears to be real easy to install and was a real attention getter. I should know, I purchased a unit.

    :D

    I got the Trainspeed unit as well to match the speeds of different engines and manufacturers. My next step is to hook up my computer interface to a small circle to get the DCC speed table going. It is maybe more expensive than a stop watch but for DCC it really cuts down the time to perfectly match the speed table.
