I found a bug in the transportation module.
The speed of the "transport-belt-ground-4" and "transport-belt-ground-5" are both the same as the express belt and not 0.12 and 0.15 like the 4 and 5 belts.
It may be asked already but how do I connect my e-rails to my electric network? I don't see a blue background like on the pictures. Or is this a bug with 3.0.0?
