What annoys me is that the crew don't seem to understand that distinction. So they passengers in the II coaches "it should be working, guess it's broken today".

I basically tell people if travelling on VIA Rail that if they don't have a wireless stick of their own, they shouldn't bother trying to connect to corporate services as the lag and dropout is too frustrating. My colleagues would be delighted with 10Mb if ping times were low, coverage basically total, bandwidth per user capped, and streaming/appstore updates throttled/blocked. I was able to Facetime for a short time with my wife who was on VIA 55 yesterday - was surprised the VIA provider's admins hadn't blocked it as they usually do youtube etc.
I have to say I still think this isn't ambitious enough.
I think 100MB/train should be a bare minimum even sooner.

5.1.2 PROCESS IMPROVEMENTS
The TSN [trackside network] shall provide a separate train‐to‐ground connection dedicated to operational applications that shall provide Amtrak with the means to enhance operational efficiency through real‐time monitoring and reporting of on‐board systems.
5.1.6 COST EFFECTIVENESS
The TSN shall help Amtrak lower overall, long‐term costs by:
- Reducing its reliance on hard‐to‐manage cellular subscriptions for train‐to‐ground communications across the fleet;
- Introducing operational efficiencies for on‐board systems monitoring that reduce costs through advance warning and analysis of mechanical and electronic defects;
- Providing a system‐wide, high‐speed communications infrastructure for a wide range of applications in the future.

I don't think you would get interference off D.C, there's no alternating , so frequency is irrelevant.Unless there was some kind of interference coming from the rectifiers in the substations.

The question is how aggressive the FCC may choose to be in enforcing its regulations to compel the railroad to suppress interference to licensed services upon complaint. It is Amtrak's own best interest to figure out how to suppress interference to its wifi offering.David Benton wrote:The DC would not interfere but neither would 25 or 60 Hz AC.

And I doubt the FCC Part 15 rules on unintentional radiators would apply.....
Customers today expect Wi-Fi as part of the service offering across the U.S. public transportation system. The Long Distance fleet Wi-Fi project builds on that success of Wi-Fi in the NEC and State Supported Services by extending the installation of Wi-Fi networks to the remaining Long Distance equipment. This program starts in FY15 with implementation on the eastern (single-level) Long Distance fleet, and will be extended to the remaining fleet contingent on the performance of and customer satisfaction with the first phase system.http://www.amtrak.com/ccurl/458/748/FY1 ... l-Plan.pdf" onclick="window.open(this.href);return false; page 17.
WASHINGTON – AmtrakConnect® cellular-based Wi-Fi service is now available to all passengers on Auto Train as part of an ongoing effort to enhance the passenger experience. Auto Train allows passengers to travel with their personal vehicles including cars, vans, SUVs and motorcycles between the Washington, D.C. area and Florida, and stands as the first long-distance Amtrak train to provide Wi-Fi.http://www.amtrak.com/ccurl/360/562/Fre ... 15-056.pdf
This marks the first phase of a larger Amtrak rollout that will provide passengers with free Wi-Fi on all single-level, long-distance train routes in 2016.
Next I heard an announcement we were stopped for a "police investigation". Now I discovered a flaw in AmtrakConnect; for so far as Mr. Google's map was concerned, we were still sitting in Sanford. Well, we know that "police investigations" take their time and details are "never exactly" forthcoming, but that "set us down"......I woke up for the Florence service stop, and found that the Map has us properly located....Now there is time to play with the phone. Since I have never come close to using the 2 gigs a month that Mr. Verizon seems to think I "need", I now tried an experiment. I signed out of Wi-Fi, and darned if the Map didn't start working - perfectly. After a while, I reconnected to the Wi-Fi - and it still worked. So I guess if you are willing to burn your own data to get it started, it will work. Would have been great to know that leaving Sanford; of course, the "flip side" was would have my Times and Journal gotten read?
