These are the South African class 18E locomotives that are powered by 3kva DC current. They were originally South African class 6E1 locomotives and were rebuilt into the class 18E locomotives with upgraded technology. Send me your WattsApp number, and I will send you photos and videos of the interior of them.
They have the option to start them simultaneously or individually. Most drivers prefer the individual start-up as it helps the software on each locomotive to link up with the lead locomotive's software. There are issues that the locomotives start pulling against each other in a case like this where you have three locomotives couples onto another three.
