Very rare before WWII as they just used baggage cars, but:What freight cars might be found in a 1942 passenger train?
Something I hadn't considered with locos using Natural gas for fuel. Do they have spark plugged ignition systems instead of diesel's compression ignition (no spark plugs or only glow plug igniters) system?Yesterday we were driving up Rt1 just north of St Augustine, Fl and spotted a fairly long FEC freight train headed south, At thetail end of the train were two passenger cars, one FEC and the other a private one.
All of these FEC trains that come thru now are running with a nature gas supplycar between the 2 locomotives
Seems the practice of "tacking" private cars onto freight trains has existed for some time, but just how AMTRAKS ban on them will affect their excursion trains, their doesn't seem to have been any news.At thetail end of the train were two passenger cars, one FEC and the other a private one.
When moving *unoccupied* passenger equipment in freight trains, it seems to be a common practice on most roads to handle them at or near the rear.Seems the practice of "tacking" private cars onto freight trains has existed for some time, but just how AMTRAKS ban on them will affect their excursion trains, their doesn't seem to have been any news.
Natural Gas/LNG isn't hydrogen. It's a petroleum/hydrocarbon fuel.Liquid hydrogen or slush hydrogen may be used, as in the Space Shuttle. However liquid hydrogen requires cryogenic storage and boils around 20.268 K (−252.882 °C or −423.188 °F). Hence, its liquefaction imposes a large energy loss (as energy is needed to cool it down to that temperature). The tanks must also be well insulated to prevent boil off but adding insulation increases cost. Liquid hydrogen has less energy density by volume than hydrocarbon fuels such as gasoline by approximately a factor of four. This highlights the density problem for pure hydrogen: there is actually about 64% more hydrogen in a liter of gasoline (116 grams hydrogen) than there is in a liter of pure liquid hydrogen (71 grams hydrogen). The carbon in the gasoline also contributes to the energy of combustion.Compressed hydrogen, by comparison, is stored quite differently. Hydrogen gas has good energy density by weight, but poor energy density by volume versus hydrocarbons, hence it requires a larger tank to store. A large hydrogen tank will be heavier than the small hydrocarbon tank used to store the same amount of energy, all other factors remaining equal. Increasing gas pressure would improve the energy density by volume, making for smaller, but not lighter container tanks (see hydrogen tank). Compressed hydrogen costs 2.1% of the energy content to power the compressor. Higher compression without energy recovery will mean more energy lost to the compression step. Compressed hydrogen storage can exhibit very low permeation
Just a clarification, Amtrak has not banned private cars. In fact, since they are a common carrier they cannot ban them. What they have done is get the tarrif changed such that they can refuse a private car if it might effect the schedule of the regular train. That generally means that a private car will not be set out in "Stafford Kansas" anymore (Stafford station closed last year) because that would be an extra 20 minutes --minimum-- to the schedule of the Southwest Chief which is already struggling to make its time. The private cars can now normally only be picked up and set out where Amtrak has normal switching, or long stops scheduled (like Denver), or a local switch engine available. Because of this the American Association of Private Railcar Owners had to change their convention location from Duluth to St. Paul. Sad, but it makes sense from Amtraks situation.Seems the practice of "tacking" private cars onto freight trains has existed for some time, but just how AMTRAKS ban on them will affect their excursion trains, their doesn't seem to have been any news.
Why is it Amtrak's fault that the NS will no longer run excursions and only allow the locomotive to be ferried over their rails? We have seen this from NS before. Everytime the leadership changes we get new rules. Remember NS are the ones that intentionally depowered the restored 611 and 1218, forcing the 611 to be restored again.AMTRAK has certainly screwed the Steam excursions like 611. Its a shame so may folks contributed to it being put back together, only for it to sit.
I think that's for the renting of their cars and locomotives for special excursion trains, not tacking a privately owned car onto the back of a regularly scheduled train.AMTRAK had announced this on March 28 about the use of their equipment for excursion use, although at that time it was unclear as to the extent. Maybe they have softened their stance (or negotiated more favorable hirage fees) with AAPRCO.
“There may be a few narrow exceptions to this policy in order to support specific strategic initiatives, for example trial service in support of growing new scheduled service. Otherwise, one-time trips and charters are immediately discontinued,” the notice adds.
I can understand them not being prepared to interfere with their scheduled trains etc. The ploblem for the private car owners is now to find any operators who will do it. Freight carriers already have enough problems with backed up trains. Any abandoned, well kept trackage going cheap?I think that's for the renting of their cars and locomotives for special excursion trains, not tacking a privately owned car onto the back of a regularly scheduled train.
