Re-assessed later sections need more work to go to B 

 Looks good, however, going from C to B is a rather big deal. As it is now I have serious problems with the sections:

 "Merchant marine"  No sources / no readable prose. This needs expansion. (or alternative needs to be removed altogether). Also unclear whether this includes river trade a major Dutch transport sectors.

 "Pipelines"   Again no source and no prose. Either expand. The dense gas pipelines to almost every home is interesting e.g. Alternatively remove.

 "Government"  again no sources. Additionally, this is not completely true as provincial wegen are under provices and local street under municipality. So this sections needs considerable expansion.

"Economics" somewhat cryptic. Is this about truck transport or also about train goods transport, shipping and air cargo? Or does it also include the economics of passengers traffic. This needs serious expansion and clarification.

 With these sections this problematic I am afraid I cannot yet promote to B level.
