If we are talking Sacramento to San Jose, two things initially come to mind: First, the state supported removing the few single track sections, so the route is double track throughout. Second, the line is near dead flat, so freight trains can maintain their speed, so delays due to slow...
The Mississippi River this far north is anything but a Great River. It is a comparatively a small river, little more than a creek to those who live along the true Great Mississippi. The dividing point between the Upper River and the Lower River is the point where the Upper Mississippi River...
Concerning the use of European signaling and similar practices: They should be approached with a large dose of skepticism. Many things they do do not work as well as they claim. Many of the US normal practices are more rugged, simpler, and more reliable than their European equivalents.
I am a Civil Engineer, and the usual is to gather up all reports and studies that have been done in the area of concern first, and then work out from there. I would be very surprised to find they did not gather all studies that they could get their hands on. Just having existing reports can...
???Not sure of where your V^3 comes into play. I do know it is there, but not at what speed it becomes a consideration. In the Japanese formulae they use V^2 up to 300 km/h, which is as far as they go with any information they let us have. Can't give you their formulae as it is proprietary...
When you go to extreme high speeds with freight trains, aerodynamic resistance becomes a major factor in the need for power, and with it extra units to pull the train. In fact, at high speeds aerodynamic resistance is THE major component of train resistance. Since aerodynamic resistance is...
There is nothing inherently wrong with this concept and route, other than its curvature. Flat is a very good thing, and low cost also was a near necessity at the beginning, as for the original we were talking about private money, not government printing press as a source of finance. What is...
Brightline trains run on tracks of the Florida East Coast, which did not join Amtrak, therefore the FEC has no contractual relationship with Amtrak. Commuter lines were specifically excluded from Amtrak from its beginning. The chance of Union Pacific choosing to operate passenger trains is...
This is not near as bad as it looks. Drag the rails in the damaged section out of the way along the track, get some earthmoving equipment out there and grade up the washout back to the proper cross section, bring in a car load ties, associated OTM (spikes, plates, bars and bolts if needed), a...
16.7Hz is not correct by the way; it is 50Hz divided by 3, so it is 16 2/3 Hz. Normal AC in Europe is 50 Hz, not 60 Hz as in the US, Canada and quite a few other places. The history of the why for the old Pennsy's 25 Hz, I don't know. Likewise, I have no idea why the ex New Haven 11.5 kV 25...
The alternative through DC would be to follow the freight route. That route is cleared or is in the process of being cleared for double stacks, so the superliners would be no problem.
There is nothing I can see changed that would result in a Midwest Autotrain being anything other than the...
