I don't know how many nights I've lost track of time reading through this site, mostly in the 'unusual locomotives' section.[1] (I'm in a rail modeling group where some of us are really into the oddballs, so it comes up pretty often there!)

Oh, wow, guess like I will have to take another look at this site in my free time (at the office now). I hadn't even heard about electrically heated steam locomotives until now (http://www.douglas-self.com/MUSEUM/LOCOLOCO/swisselec/swisse...).

My personal favorite is the articulated locomotives, especially the Klein-Lindner system: http://www.douglas-self.com/MUSEUM/LOCOLOCO/klienlindner/kli...

It probably took me about a week to get a full idea of how it works, and I'm hoping to create a model to help myself really understand.

Same - I first saw the 'N-wheeled vehicles' posted to HN years ago and lost a good day to it: http://www.douglas-self.com/MUSEUM/TRANSPORT/nwheelcar/nwhee...
