No matter how careful you are there is always something that goes wrong. I have some photos of trains and things that relate to trains. Here are a few. The Scale Disneyland Railway was always afavorite of mine.I especially liked the tunnel and the Dinosaurs at the original Disneyland in Ca. The locomotive Patterns for castings were built at the Southern Pacific Shops in Sacramento Ca. . A good friend, John York, Built a few of them. There are some great locomotives at the Sacramento Railroad Museum including the C.P.Hutington from the old Central Pacific. There is a short line they run locos back and forth there.
There is another Scale Railway I  love and that is the Portland Zoo Railroad. My good friend, Cecil Davis, retired from running UP Big Boys and operated the little Steam Locomotive there. He pulled a train of open excursion cars from the Zoo to the Portland Rose Garden and back after a short stop for a breathtaking view. . The Portland Zoo Railroad had it's own Railway postoffice cancellation and could stamp your letter and
mail it. They operate a couple of diesel trains now, one is the Zooliner based on a 60's streamliner  and the other is a diesel engine pulling the old steam Excursion car set.
There is another great train that I saw in Laughlan, Nevada, Right across the river from Bullhead City, Az. The train runs about a mile around the Railroad Casino and hotel. It looks and sounds like a real steamer, but it is fiberglass. This is a great place if you like trains. They have a museum of photographs, a shop that sells great train stuff with an LGB layout overhead, and some great stuff all over the casino.  There are another pair of trains parked in one of the three casinos at Pimm, Nevada. They used to connect the casinos together and run through them, but the beancounters replaced them with a monorail and a rollercoaster that goes through one of the casinos. Now they are a static display(don't you love that word)  overhead.
There is a warm spot in my heart for the old steam logging and street engines. I like the old Mallets of the southern Pacific and The UP Bigboys, But they can't hold a candle to a two truck Shay puffing up a grade, flat out at 10 mph and sounding like 50!
There are a number of Shay, Climax and Heisler Locomotives in the Pacific Northwest, Even a few left in Central California.
In fact one of the early horizontal boiler shay two truck units is at the Michigan California Lumber Co in Camino, Ca. I will add photos of it as soon as I find them. There is a Caterpillar Tractor Engine powered Locomotive there too.  There is, or was a Steam powered crane at Clarksburg, Ca. at the Delta Sugar Co. Refinery. I used to light the boiler at daylight and get up steam so the operator could switch cars around with it. We used t for a switch engine.
 There are a couple of great engines at the entrance to the World Forrestry Center at Portland, Or. Near the Zoo.
