Why is the center rail so much more grimy?

RailgonOGR Forum Member

I was running at the club last weekend and slowdowns caused by dirty track started to show up. What I have consistently noticed is that the center rail is much more grimy than the outer rails. Why does this happen? I run my finger on the outside rails a couple of inches and very little black grime. Run my finger and inch or two on the center rail and it feels tacky and leaves a heavy black line. I can't believe this would be from over lubrication of the center rail pickup rollers or locomotive gears. Most operators run modern equipment and no smoke. We do a thorough track cleaning twice a year, and it seems to only take about 3 months for the dirty center rail to start appearing again.

Thanks for your replies.
