>>1743049Exactly wrong.
>>1741880US freight cars don't have any MU cables whatsoever. Lead power is coupled with the AAR standarized 27pin cables and DPUs are controlled via radio using system such as Locotrol. Radio controls are a fairly new thing. In europe radio control is not used, as train lengths don't reach lengths which justify it. The swiss made some experiments, but it went nowhere.
To underline my original point
>>1742095This one and...
>>1742103...this one are the _same_ locomotive. The single unit has these connectors on the front which allow for MU operation with another of its kind. The twin section version simply has these cables between these sections. Each 'half' can actually operate as a separate unit. The only difference is lack of cabs. But some 'singles' were made out of a half of a double, if the other half crashed.
The sole reason why the double exists is that the double exists is that polish railway code forbade running unmanned locomotives. This has changed recently and private operators now actually run the singles in MU configuration. Pic related.
Can't speak for other ex-commie countries tho.
