Hi guys  I started calibrating the speeds of my locomotives with Itrain. It's a long time and I don't have time. I have to think about preparing the move. I thought about cheating to go faster Here is what I intend to do : - at step 126, enter the maximum locomotive speed forward and backward - in step 1, enter the minimum speed at the start, i.e. 1 km/h - proceed with the application Itrain calculates the speed curve and a beautiful diagram emerges. It's very fast Is this valid? Is that correct? I wonder about the question Thank you guys Thewolf Edited by user 29 September 2019 14:11:35(UTC)

Depends the speed to simulate like the prototype.
If you have 28 speed steps in the decoder it makes also difference from 126 speed steps.
For example...a shunting diesel locomotive V60 do have maximum 60 km/h so try to set difference between 28 and 126 speed steps in the layout and check what it feels good for you. |

Each locomotive has its own speed curve.
By proceeding in this way, all locomotives will have the same speed curve, i.e. straight ahead.
I give up the idea

Something I've done in order to match speeds of two locos was to switch from log to linear curves. Then it was only a question of setting Vstart (CV 5) to 1 (or higher if the loco doesn't start moving at the smallest speed step) and Vhigh (CV 2) to values that yield the same top speed for both, equal to the scale top speed of the prototype. Don't know about ltrain but JMRI makes it very easy to adjust all intermediate speed steps with a click of a button.
Leave the locos running for a while, the top speed changes as they warm up so fine-tune CV 2 on the main to get the desired top speed.
