Hello Everydaymatters,
Although I have not done this yet, I have been researching for months (for a future Canada trip). The easiest way from Detroit to Windsor is through the Tunnel. There are 2 options here. You can drive or take the Tunnel Bus. The Bus actually stops and you walk off the bus to enter customs on foot. If you must do Taxi, then only take the taxi to the Tunnel, ride the bus through the tunnel, then get a taxi on the other side to Windsor train station.
Now on to the advantages of riding Via in the corridor: The Via Rail Corridor is the equivalent of our NorthEast Corridor, except its NOT electrified. This is advantageous because there are MULTIPLE trains a day on each segment. Just like our NEC, the Via Rail corridor is the fastest stretch of track in Canada, especially between Toronto and Montreal. So you have more frequent trains and faster track, this is the first point.
The REAL time saver in my opinion is crossing the border. If you compare a Via Rail trip to an Amtrak trip TO Canada, the slowest part of the journey is crossing the border on the Adirondack or the Maple Leaf. And near the border, these trains travel on some of the slowest track in the entire Amtrak Network (compare the the fastest track in via rail network).
The next advantage of the Via Rail Corridor is the fast connections (because of multiple trains a day). You must factor waiting time into a US - Canada journey. There is a 6 hour delay in Buffalo Depew between the Lake Shore Limited going east and the Maple Leaf going north. And since the ML is NOT a corridor train it could also be hours late. To get the Adirondack the delay is even worse, almost 24 hours. Compare this to the delay between Windor-Toronto and Toronto-Montreal, which can be as little as 1 hour.
The final advantage of Via Rail is the Rennaisance equipment (if your train has it). If you can catch the twice daily express trains (the ones with the fewer stops), you are guaranteed to have the REN equipment. The Ren equipment is the former nightstar rolling stock from england, basically an overnight version of the Eurostar. If you travel first class on a Ren train, you will probably have a lounge car (a european one at that).
Final advantage is stopvovers (but least important)..... There is a massive las vegas casino in Windsor. Now even though I am not a gambler, I love casino rooms because they are subsidized by the casino. So for HALF the price of a motel in Albany, New York, you can stay in a palace in Windsor for a cheaper price and with a Las Vegas quality buffet for a meal. You need to factor in how nice (and cheap) the stopover is.
Now lets say you DO this stopover in Windsor, instead of further down the line.... You can then leave on the 6am Toronto train, make 2 connections, and be in Quebec City (on the opposite end of the corridor) by that evening.
Remember how frequent the trains are in the corridor, so if you combine your tickets into one itenarary (like on Amtrak), then your connections are guaranteed, meaning if the train is late, Via Rail must put you on the next train 2 hours later etc.
I actually called Via Rail and asked what would happen if I had all seperate tickets (express savers) and I miss a connection. She told me in most cases, they will still put you on the next train, But if you want to have 100 percent protection, combine your tickets into 1.
With this in mind, you can even risk the 45 minute connections if you dare.
To give you an idea of how slow crossing the border on the Maple Leaf is.... I calculated that if you are coming east on the LSL arriving in Buffalo Depew at 9am... You can get a taxi downtown to the bus station and take the Niagara Falls Bus to the border, walk across the Rainbow bridge, take another taxi to the via rail station, catch the earlier VIA Rail only train to Toronto, and arrive in Toronto 5 or 6 hours earlier than the Maple Leaf. Depending on the season, you can get a taxi to the airport a could of miles a way in Depew, and take a direct Niagara Falls bus to the border, even quicker.
Doing it the amtrak way, you must make a stopover in toronto because the maple leaf arrives at 8pm ish...... if you did the Windsor stopover instead, you can use the second half of the day to ride the complete corridor to QUEBEC. Sorry, I am assuing that Quebec is the final destination here because its the furthest station down the corridor (and its what I was planning to do).
