Bob's Fun Run

I want to thank Bob for the great time I and my family had at his place last week. My grandson was overjoyed at being able to run the "BIG" train. I have never seen so much equipment and rolling stock in one place outside of a toy store. That looks like quite a few years of collecting and hard work at assembling the layout. I got the feeling from the conversation that it was still "A work in progress". The snacks and talks were great fun and I picked up a few pointers to get my old steamers running a bit better . Thanks to all.

I just picked up a Lionel 3927 Track cleaning car in pristine condition. As to those cleaning pads - is there some solution you put on them or do you run them dry? Do you wipe the tracks down with something beforehand to maximize the value of running the car? And procedural advice appreciated.
