There are now two deals if you are travelling to and from the conference in part or completely by train:

1. 10% conference discount. More information on the conference Travel page.
2. 60% limited time offer with a deadline of April 25th. More information on a devoted page on the Via website.

Unfortunately, it doesn't look like you can combine the two deals but if you can reserve right away, and particularly if you need to travel outside of the conference discount date range, then you can get the 60% discount. Otherwise, don't forget about the 10% conference discount.

Happy travelling and we'll see you in Kingston!
