How to calculate the Arrival time for Time History Analysis?

For the time history analysis, how do I arrive at the arrival time?

It depends on the velocity of the train and the distance between the nodes.
Say there are nodes spaced 0.5m and the velocity of the train in 50m/s,
then the arrival time for the train for the second node would be ( v = d/t = 0.5/50 s = 0.01 s )
so for further nodes 3, 4,5 the arrival time would be incremented with 0.01s (i.e 0.02, 0.03 etc )
