Here is a weird but interesting question for the railfans!!

Suppose, a train starts moving from a complete halt. Now, we know that a train consists of multiple objects (coaches) joined together. So, there must be some time difference between the movement of the loco and the last coach of the train. So, does anyone knows what is that time difference?
Let's say
...
more...
the train is a 22 coach LHB train being pulled by a WAP-7 loco in a straight track (not a loop line).

Great
I don't think there is any time difference. All couplings are almost rigid and having nil elasticity so last coach start moving at same time when Loco start moving. Difference can be there in fraction of micro seconds only.

I agree with you. However, the difference maybe negligible in the case of passenger trains but it increases in the case of freight trains if you notice carefully. As we are talking about passenger trains here, there is still a time difference which is more than one second in passenger trains. As I think.

Depending on how much is the load and what is the HP of the Loco assigned. it can vary from microseconds to a noticeable but little few seconds.
