Xbox Ntp Redbank Carriages

The Redbank carriage sidings have an issue whereby if you separate the existing rakes, a black/brown corridor appears between the two carriages/vans you separated. I went to the sidings to sort out each different type of car, and as I'm pulling apart a standard formation for the sidings (first, standard, freight) another box/corridor thing appeared. These things will go through cars and locos should either be between the crossover between the two separated cars. They can be moved through freely, on either foot or in a vehicle, but are rather unsightly. I have attached pictures

 

I think you may have released the entire space time continuum!
