problems with certain routes

[deanmalmgren]

This is a little bit of a placeholder, but I'd like to get a sense of whether this is a network-type of an issue or whether there is something consistently broken with some of the routes. I'm getting emails that look like the following for lots of trains:

Exception raised when querying the rail time tracker for trip UP-W_UW10_V1 traveling from ELBURN to OTC.

Response (200) back from server:

{
  "train1": {
    "error": "There are no trains available for the selected stops.  Please change your search and try again.",
    "status": 0
  }
}

Looking at the dates on which we get this error, it appears to be intermittent. Probably we need some better error handling in this situation so we can diagnose what's going on. Might be good to add the tracked_times to the error message.

• UP-W_UW10_V1 : 2/2 2/5 2/6
• UP-W_UW11_V1 OTC to ELBURN: 2/6
• UP-W_UW53_V1 KEDZIE to ELBURN: 2/2 2/5
• UP-W_UW73_V1 MELROSEPK to ELBURN: 2/6
• UP-W_UW70_V1 ELBURN to OTC: 2/6
• UP-W_UW68_V1 BERKELEY to OTC: 2/5

Train 10 doesn't start until 4:48. Perhaps all of these routes are starting early for some reason...
