I have both the Amtrak and the UP track cleaners, and they are both in good working order, I would like to get the pads for these units or find something to replace them with, I have been collecting trains and putting them away since the early seventy's, never had the space or the time to set them up and now with I am retired and I am going to start to get into it and out of my wife hair, so if anyone knows where or how to replace these pads I would be very grateful, Thanks
