(I know, I know, while @DaTrainGuy is working on an official remaster, he allowed me to make this, and we've more or less decided to see whose remake is better)
Life is good on Sodor in late 2002, except for how the winter is getting pretty bad and rough, and also a new facility at Cronk is making everyone weirded out. However, things take a turn for the worst at the start of January 2003, forcing BoCo, his crew, and the rest of the engines on Sodor to take great measures to survive a horrific, freezing infection and a monstrous former friend.
