Train acceleration and top speed

Trains accelerate faster or slower based on their mass, air resistance of the wagon in front (usually a locomotive but it can be anything), and total number of wagons, including locomotives. Furthermore, the top speed varies based on the fuel used.

This calculator lets you define all of the relevant information about your train and determine its top speed, as well as precisely how long it takes to reach that top speed.
