Some pics of my re-modeled Lionel O27 Atlantic. Small, but just what I needed to pull a short mixed freight/combine 20 miles out to Clarksville and back. At Clarksville (staging) this guy is required to do his own switching, hence I needed a truck mounted Kadee on both ends. I added valve gear from an A-5, a proper outside bearing trailing truck, applied grabs, operating(but non-functional) cut levers, and squared off the front cab corners to give a more east coast look. Also a scratch-built tender. Got rid of that ugly Elesco feedwater heater too.
It may be fair to ask why anyone in his right mind would put this effort into what is still really a toy. Setting aside my mental state (I do play with toy trains) there are maybe 3 reasons:
1. I had it.
2. I like to tinker.
3. I'm really cheap.
