"CLF itself doesn't have the right to ignore KWG's priority on use of the surface of their own claims."
Correctly so?
I believe that KWG has first priority when there is a conflict but what was implied by the last ruling is that the two parties should accomodate each other.

Question is = Is it physically possible?

Road could go along side of railway but what about bridges. Can they share bridges? Is the corridor wide enough to construct wide enough bridges to accomodate both modes of transport.
Over and under bridge?

What about cost?
It seems like unnecessary duplication if anyone asks me just because two kids do not want to play together. Share just the railway, period.

The more usefull road imho is still original E/W.
