Control of Diesel Locomotives

[wayne]

1) What signals or data are sent or conveyed by all the connections one can see between diesel locomotives in order for the control to be from a single unit (usually the first one)?

2) How are the DPU units controlled from the lead unit?

1) TRAINS has published this at least once. I don't remember the issue(s) and I think one of the Diesel Spotter Guides also has this in it.

2) Radio. A very secure computer controlled connection.

and there was a nice thread on here which kind of beat the thing to death -- not too long ago. 'MU' or something like that...

Look around page 7 or 8. I started the thread, titled "MU Operation". Last post was somewhere around Mar 4.
