Now run each loco at some ridiculously high throttle setting to determine which loco runs *faster* at that setting.Note this setting, and also the time it takes to travel the track section. For each locomotive, determine which throttle setting gets the locomotive moving from a dead stop.
If you are using DecoderPro, the easier method is to use the Match Ends command in the Speed Table tab. If using a speed table, set CV94 to 180. When speed matching two locomotives on parallel tracks, making them a consist simplifies control of both! If you typically use the 28-step mode, the decoders can be fine-tuned in that mode later. Set the command station to use the 128-speed step mode. This step may not be needed with TCS or QSI decoders. This clears the Vstart, Acceleration Rate, Deceleration Rate, Vhigh and Vmid values. If these CVs are NOT zero, their effects will adversely influence your observations any effort will be fruitless. If you do not have DecoderPro, read the CVs below in each locomotive and make note of them before altering any CV. If the locomotive is not in the roster, create a new entry and read the decoder's CVs. Trying to match a slow locomotive to ones which are faster will be frustrating. That allows you to adjust speeds on your workbench.īefore beginning determine which locomotive runs the slowest at a given speed step. Determine which locomotive starts at the lowest throttle setting, and which locomotives run the fastest at a high throttle setting.Īnother possibility is to use a test stand with a speedometer, such as that which was offered by Bachrus. This will need to be completed twice for each locomotive, using different throttle settings. With this method, determine a locomotive's speed by measuring the time required to travel a known distance. A double tracked section of mainline can be used to compare two locomotives simultaneously. Clean the track and wheels beforehand to eliminate any pickup issues. Measure out a known distance on the layout, the longer the better. 
For N scale 15-20 feet is needed, adjust this method to your scale. Speed Matching involves running locomotives on a long section of track and timing how long a locomotive takes to travel a defined distance.
