Does anyone know if Bachmann will change the running gear of an older model GS4, using a Bowser replacement and then install the correct DCC decoder? I know I could send the Locomotive in and get the correct DCC decoder installed, I just do not know if they would change the running gear. Also?

 Are you planning on bringing back the two train sets I mentioned, above?

I have two GS-4's, one daylight colors and one war baby. As of yet they have not been run, but have been sitting aside for quite some time. I am now in the process of revamping my layout and getting my running gear operational. I have Digitrax DCC and most of my running gear has now been converted to DCC. What is the best method for doing so to the GS-4's? I do not have the ability to do it, but I do have a local dealer who does. What I would like to know is what decoder you recommend? And, what is the best method to install the light in the rear of the tender? Also, I have the standard sheet with the blown up picture of all the parts, but I do not have any details on the best method to disassemble for cleaning or lubrication  Is there any printed material on the maintenance to the locomotives for a hobbyist?

I have a Hornby Mallard in Ho, but it finally needs some support/repair work on it. Does Bachmann support/repair Hornby? If not, how do I find them, as i have already tried and got nowhere.

To Bachmann: is it possible to buy 4 model trains with only enough track for display? They would be for my grandsons, who just happen to live in Philadelphia. I do not live there, but am trying to figure a way to save some money and shipping costs, legally!
