I found a couple neat poster checklist PDFs by accident (there is a valid URL, thomasandfriends.com/minischecklist , but if you google it you will see my page instead as the first or second result 
).
There is a 2015 poster that has all the 2015 engines (except the DC Super Friends), the Advent Calendar, Warriors from the 50-pack, and Dirty Percy from the Twist-n-Turn Stunt Set.
Then there is the 2016 poster with all the 2016 engines, the Advent Calendar and Dirty Percy again, the Glow in the Dark and Insect (30-pack) engines, Thomas and James from the Motorized Raceway set, Platinum Thomas, and the 4 engines from the Launchers. The second page has all the DC Super Friends (looks like it has all the ones we know about, except it's missing Batman Diesel from the Comic-Con pack), including Clayface Bill from the Batcave Playset and Green Lantern Gator (who is also labelled as being in the Batcave Playset; probably a mistake as he's actually an exclusive to the DC Collector's Wheel) and all the SpongeBob engines.
Notably, the 2016 checklist is missing the Tootsie engines, and the front still doesn't mention Classic versions of Rosie or Belle
As long as I'm posting... I've been thinking a little bit about adding pictures to my checklist web page, but I only have about half the engines and I'm not really planning on getting many more so I won't be able to take pictures for all of them myself. Does anyone know if there's a good resource where I can (legally and ethically) get pictures for the rest of the engines (or all of them from one place)? I know the wikis have pictures but wasn't sure what their policies were for reusing pictures (jdogman I'm looking in your direction...).
