Have a question for anyone knowledgable about trackbed maintenance, specifically as it pertains to in and around paved gradecrossings. I've noticed at several of the local grade crossings on the CSX (ex B&O) main through town that there appears to be a significant dip or give in the rails in the short distance, maybe 10 feet or less, on either side of the grade crossing when a train is passing over. It would seem that the engine crews would feel a sensation similiar to going over a bump at these locations. Everything looks OK and level when there are no trains. It seems to me this condition could be relieved by placing extra ballast underneath the tracks in these areas. Is this play normal or desired for some engineering reason? Is there an accepted tolerance for this condition? I've seen enough of a jump that it is not inconcievable to be that this condition could cause a derailment, expecially on some of the faster traveling freights or Amtrak's Capiol Limited.
