You can shuttle from Winnipeg to Grand Forks for $145 CAD on Ridebooker.com. And the shuttle gets to Grand Forks at 9:30 PM. The Empire Builder departs from Grand Forks at 12:57 AM, so it's only a 3.5 hour wait.
Well, that's a service I was previously unaware of. Definitely some plusses and minuses.
On the plus side it looks like they will drop you off/pick you up at the GFK train station.
On the down side...that shuttle that gets you to Grand Forks at 9:30 p.m....well, the train station doesn't open until midnight,
so have fun waiting around in the cold until then...unless you get dropped off somewhere else in town (a 24-hour McDonald's?)
and get a taxi out to the train station later, which adds to the cost and hassle of this transfer. And of course if you want to head
westbound the train doesn't leave until 5 a.m. which really makes this an inconvenient transfer.
Returning to Winnipeg, if you are coming off the #8 you will have about a 5 hour wait, but at least you can stay in the train station,
as unpleasant of a place as that is (NO food or beverages available, but at least it's heated with a bathroom). If you're coming off
the #7, then theoretically you only have a 1 hour wait but given the reliability of the EB this is an iffy proposition. If you miss the shuttle
you get to spend the day in Grand Forks, I guess since the next departure isn't until 6 p.m.
And another HUGE downside to this...this footnote:
This is a minimum occupancy service. The service operates only when there are at least 4 people confirmed. Decision on whether or not the service operates is made 48 hours before departure. If the service doesn't operate all guests receive a 100% refund.
Depending on where you are coming from, you may already be
en route to Grand Forks/Winnipeg by the time your shuttle is canceled (unless you are traveling in
a party of 4 or more, in which case your shuttle trip is guaranteed.)
So this is better than Jefferson in some ways, but it still pales in comparison to what this segment really needs: a dedicated Amtrak Thruway connection.
