Do the Amazon Trainz DLCs work

So, after I went back to Pre-SP1 TS12, I thought that I would miss out on the Trainz DLCs, like the Blue Comet and the T1. But after I went on Amazon, looking for Trainz stuff, I saw that the Blue Comet and the T1 were on Amazon, and were released Pre-SP1. I was just wondering if these worked with TS12 Pre-SP1 or if they even work at all.
