Its a cold and rainy day here in central Texas today so I felt like digging through my photo's for a few shots of some earlier trains than my normal post war / MPC Lionel. This is just for fun and for a little something different
First from early American Flyer (Chicago Flyer) this is a "Hummer" locomotive and dates to about 1924 iaw the green tender. The loco might date as early as 1922 with a black tender and tenders are easily switched over time so its from 1922-24 in that time period. Clockwork with a fixed key on the loco. Its just about a century old and still works ok. In terms of the "crew talk" module, its amazing...put your head near the track and whisper what you want and it will "say" anything your imagination requires. 
.Here is a Hafner 1010 locomotive, also clockwork as you can see the key. Hafner never made anything but clockwork locomotives, Mr. Hafner believed electric trains were too expensive to be toys. The 1010 was made from 1938 thru the 1940's and 1950's both pre and post war in a wide variety of colors and trims.
This is a Japanese tin toy from the 1950's. It is by the manufacturer "Alps" and was battery powered. A single "D" cell in the boiler took care of the power. Its modeled after a NYC 0-4-0 Tank type switcher but whether or not the NYC had any locomotives like this is unknown to me.
Well that's it for me today, Enjoy your weekend and I hope it doesn't rain all weekend where you are (for me, not much hope).
Best Wishes
Don
