This is a good but tricky question.
Original they had the 3 PTC's on Voyage. They sold 2 of the PTC's before the start of the 2010 season and only had 1. When they realized they were not ready to use the TL's for 2010, they took 1 of Ravens 2 PTC's off of it and refit it for Vogage. So then Voyage had 1 original train, and a retrofitted Raven train. Raven ran with only 1 PTC for the 2010 season.
I would assume they still have the 3rd original PTC unless they sold it after the season was over last year. Can anyone confirm that? If not, I think they would only need 1 additional PTC for 2011. Whether that would be a used PTC or a brand new PTC I have no clue.
The way I read the article they were getting 2 brand new PTC's for 2011?
