If at first you don't succeed

Remember yesterday's track? Well this was Isaac's attempt at an improvement. The problem was that he didn't really solve the problem he had yesterday. He did add a level crossing into the middle of the loop, but you still had to reverse you train to return to the sidings. But the siding loops have become a wonderful arrangement with the addition of a bridge and a second siding.

Maybe, like many of us, Isaac doesn't want to tackle the real problems and gets busy working in the things that work anyway.
