Hi Just thought you might like to know that i have found an online switching puzzle at http://www.bekkoame.ne.jp/~ishmnn/java/trainpuzzle.html Though it may be frustrating because i cannot solve it.Please do tell if you work it out.It does take a minute to load so be patient. There is actually an even harder one that has i think 3 car on each locomotive! Many thanks Pavariangoo[:)]
