Image Background Cancel PLESE HELP!

Hello everyone! I have a quick question about how to achive an image style in photoshop. I have many pictures of rollercoasters and I want to cut a coaster train out and put it onto a background. I have tried using magic wand, ect but it does not give good results. I am wondering if maybe there is a way to cancel a color in the picture and replace it with another color (IE. turning the sky yellow)

Here is an example of what I wish to achive.

Thank you all so much!

Never post the same question in more than one forum. Your question is actually less likely to be answered when you do that.

As for your question, you most likely won't be able to get that look with the wand or color range selection command. You will have to cut out the foreground manually either with the pen tool, the extract command, or the lasso tool.

You will find plenty of tutorials on the www.teamphotoshop.com tutorials section to help you learn how to make many different kinds of selections.
