The HNTB study completed in 2007 does illustrate that a short line operation could be modestly profitable. Aggregates, propane, and oil are still in the mix of potential commodities.
gpcog, this is an excerpt from the HNTB study (pg E-5):
"Based on this exercise and an understanding of current rail freight business, we postulate that the Mountain Division could potentially serve several gravel pits and rock quarries located on and very close to the corridor... ...Other commodities such as cement, propane, building material and petroleum products have some small potential but not in sufficient volumes and likely not competitive with existing trucking services.
That makes it pretty clear: HNTB concluded that the chance of getting any business other than aggregates is slim to zero. (However, I'd be interested to hear more of the possible projects you refer to and how rail would make a play for them.) Which brings us back to what is touted as THE (only) viable revenue source for the line: Aggregates. Consider these points:
* The HNTB study states that "The aggregate operators would need to furnish their own rail cars"
* The HNTB study indicates that projected revenue would need to be $600 per car for line viability given the projected volumes.
In other words, shipper costs would be $6/net ton
on the Mountain sub portion of the haul. Add an additional $3/NT+ for furtherance to any PAR destination, e.g., the former Cook's Concrete in Scarborough for offloading. Then add in the cost of the car (call it $3/NT)... it's going to cost a shipper ~$12/NT to move their product by rail. Now, go to the 2005 study entitled Mountain Division Rail Freight Study completed by your organization. The interview with the owner of Maietta Construction indicates that the rail cost would need to be below $3.50/NT in order to be competitive in the Portland area. Let's say he was sandbagging a bit and that there's been a bit of inflation since that study... call the break even $6/NT. Perhaps I'm missing something, but how would rail have a snowball's chance in Hades with such a cost disparity?
I've never had (but wish I had) a sales negotiation go like this: Shipper: I can't afford more than $6/NT. Railroad: I understand. How about $12/NT, then? Shipper: It's a deal!
