VTG: German Rail Can’t Absorb All Rhine Cargo Diversion

The admission from a rail operator itself is the signal here: the Rhine's low-water problem is not being solved by modal shift, merely redistributed into an already constrained rail network. That matters most for shippers of bulk and chemical cargoes that depend on barge economics, since a full train's payload sits below a standard barge's, meaning diversion carries a structural capacity penalty rather than a clean substitution. Whether rail maintenance eases before water levels recover is the open question, and it is the kind of squeeze that shows up as freight cost and delivery timing risk rather than headline volumes.
