thanks for this "new" information

i will check this out before i proceed further - i have a maximum distance of 28.5 inches

let me restate this - imagine a compass with these measurements

north and south compass points - no problems - unlimited space

but

east and west compass points - train & track must operate with a maximum distance of 28.5 inches

later in the day - i will make photos of the area and repost

thanks - rdeal
