I’m not sure if I’m understanding your comment correctly, but please don’t say that about vehicles from more than four years ago, before the new connectors were implemented in the game. It would definitely be faster to replace them yourself rather than waiting for a response to your comment.

is there a power cable connector for charging it

IDK why it looks like Russian offroader "UAZ")))

Very cool!

Thank you! I will continue to study English!

Your English is pretty good. Your creations are very useful and i find your train cars to be the best. Keep up the good work! :-)
