Hi,
I'm currently planning my trip from London to Glasgow. For this train, a reservation is required, but I can't use the reservation tool from Interrail for this reservation. I also tried to make a reservation with ACP rail, but this product is not available in the Netherlands. I searched for other options, but I could not find a website/app where you can only buy a reservation without a ticket (because I already have a Interrail ticket). Does anyone has experience with this?:)
