From the (Portland) Oregonian:
Rx Express heads north for drug buy
The caboose end of a Canada-bound Amtrak train hosted a protest against high prescription drug prices Tuesday on its way through Oregon.

California-based organizers chartered two privately owned rail cars and added them to Amtrak's regularly scheduled Coast Starlight train. They nicknamed it the Rx Express to draw attention to Canada's bulk purchasing of drugs -- an approach they say would bring Americans big discounts if the U.S. government would copy it.
