Surely they are saying that. This the text of an email from Virgin:
We're changing the way our Railcards work. From 6 September 2015, Railcard holders will no longer be able to use Off-Peak, Railcard discounted tickets on Peak trains on the Virgin Trains West Coast Mainline network.
Here are some FAQs below.
Q: What is happening?
A: We're making changes to the use of Railcards on Virgin Trains West Coast Mainline services. Railcard holders will no longer be able to use Off-Peak, Railcard discounted tickets on Peak trains on the Virgin Trains West Coast Mainline network.
Q: Why is this happening?
A: We're doing this to help simplify our fares structure and bring us in line with other long distance train operating companies.
Q: When is this happening?
A: From Sunday 6 September 2015.
Q: What does this mean to me?
A: If you buy an Off-Peak ticket for a Peak time train using a Railcard discount before 6 September, this change will not affect you. If you're looking to buy tickets after 6 September, don't worry, you can still get great value Advance tickets with your Railcard for Peak time travel. We have just completed refurbishments on our Pendolino fleet to create an extra 5,500 Standard class seats a day, so there are plenty of seats available on board our services.
