hi, I am new to this. I have just purchased a train layout, it is automated with fleicshmann locos. I couldnt afford to puchase the fleicschmann locos (I need 12 in total to get the board working properly). The fellow I purchased the board from, said that I can purchase read switches and install them on the board, and place a magnet under the train (not a fleischmann), doing this, it will allow my normal trains to function on the automatic train layout, so I can sit back and watch them all go around. Problem is when I attempted to purchased the read switches, they are sold as "normally closed" or normally open. which ones am I suppose to purchase. and there is a huge price difference here in australia. the closed ones are $1.50 and the open ones are $5.00. And I need about 30 apparently. Can anyone assist me with my enquiry.
