Hey all!
Over the last few months I've been thinking about mail traffic in the U.S. Amtrak's previous involvement in mail & express has been discussed before and the reason why it was eventually abandoned has also been discussed. To put it simply Amtrak always moved mail and express since its creation in 1971 as there was a precedent of moving high-priority shipments cross-country by rail. Long distance passenger trains with the additional costs of providing food, bedding, and lounge areas are almost guaranteed to be unprofitable unless you jack up ticket prices so much that no one would be able to ride. Mail & express shipments helped to offset these expenses and as was the case for many trains before Amtrak actually made some passenger trains profitable. It was common to see long sets of MHCs at the head end of Amtrak's long distance passenger trains back in the early years (Material Handling Boxcars - specially-built boxcars for high-priority shipments with HEP connections between the cars to allow locos like the F40PH to be able to provide power to the coaches). Notable examples from that period are trains such as the Southwest Chief and the California Zephyr throughout the 80s, both of which would have at least 2-5 MHCs up front along with the baggage car, and maybe even a few more if demand required it.
Eventually Amtrak got into the perishables and trailer business with reefers and roadrailers. The freight railroads (who host Amtrak on their tracks for a fee) complained, claiming that Amtrak was taking business away from them because of their mail and express program.
Let's pause for a minute here and consider this: Huge freight railroads which run multiple intermodal and reefer trains a day and which can commonly be from a mile to 16-18,000 feet long claimed that a daily passenger train with a 30-car limit (at least 9 of which is taken by regular passenger equipment) is going to take away from their business. How much business can a single 30-car train possibly detract from multiple daily 16,000-foot trains? That's one instance I'll call "Bull" on the freight railroads.
Anyway, the courts ruled in favor of Amtrak because of the already-established precedent of high-priority shipments being shipped on passenger trains. Now Amtrak needed to set out and pick up cars of express shipments at various stations along its routes, and it depended on the freight railraods to do the switching. The freight railroads wound up delaying Amtrak's trains by several hours with these switching maneuvers (you can make a conspiracy theory out of that if you want but I'm not here to talk about that) and this affected Amtrak's ability to keep time all across the country. It got so bad that Amtrak's President at the time (I think that was back with David Gunn?) eventually gave up on mail & express and stopped it altogether, claiming that it was interfering with Amtrak's purpose first and foremost to transport passengers with timely and reliable service. This decision to cut mail and express resulted in some trains getting cutbacks and a few others being all out scrapped.
Now I've seen conversations at various locales and forums as to why Amtrak doesn't revive mail and express or the logistics of doing that and the cons have usually been in the form of the cost to invest in the infrastructure such as sorting and storage facilities to handle the traffic and the fact that Amtrak is a skeletal system at best and just doesn't go to enough places and run enough trains to make the service profitable.
Here's my thinking: if scheduling, infrastructure, and a lack of station stops is the problem, why not reinvest in some old tech? Like say RPOs and mail cranes along the right of way? Workers can sort the mail en route and drop off presorted mail deliveries at multiple locations where Amtrak doesn't stop with the train in motion because of the cranes along the line. Local mail workers from the towns would be on hand when the train passes through to load waiting mail onto the cranes and to pick up the mail from the passing train to take back to the local post office to be further sorted for delivery. Additional mail could also be transferred at the stations where the train does stop where sorting could begin immediately. This way more customers along the line can be served at more locations than what was done previously. There would be no switching at any of the stations so timekeeping would not be an issue any more and any mail from Chicago to the end destination like Los Angeles on the Southwest Chief could be sealed up in a boxcar at the end of the train only to be opened upon arrival at the terminus. Anything like perishable shipments and roadrailers would be end-to-end service only to further eliminate the issues of switching cars mid-trip.
What do you guys think? Could that actually work?
