With all the discussion and speculation regarding the resumption of Amtrak's Maple Leaf, I thought it might be helpful to post this guide to GO Transit's current Niagara Falls service which can be used to connect with Amtrak at Niagara Falls, NY. It also provides some insight into GO service for those not familiar. There has been speculation that these trains may replace or at least supplement Amtrak/VIA service on the Canadian side.
