One more on the topic of a resuscitated
Niagara Rainbow via Detroit: if Amtrak would wish to use VIA/CN rails through Ontario (the current VIA passenger route, which as far as I can tell is faster than CP's parallel route), there are only two connections from VIA to the Detroit River Tunnel. One, the
Essex Terminal Railway (proudly a 10 mph railroad), is essentially at the doorstep of Windsor VIA but would require a backing move to actually access the current station. The other is the CN Chrysler Spur, which any remaining CN freights take to access the tunnel and CN (ex-CASO) Van de Water Yard. Both appear to be slow routes.
Until Windsor, VIA, the Government of Ontario, CN, and CP come to an agreement on a better station location, maybe the answer is for VIA to cooperate with Amtrak on a station & clearance facility near the
Tecumseh Mall.
