I have 47 wonderful 10 x 15 size kodachrome train slides from german railway. There are 22 slides of electric locos and trains, 7 diesel slides, 3 tramway slides and, thats cool, 15 slides of our narrow gauge steam powered commuter trains! You can find them only in Dresden in normal daily service! Most slides are taken on sunny days and looks very good. I want to trade. I´m looking for north american train slides, if possible also 10 x 15 and sunny.
