Hello All! I am the recent recipient of a Marx train set. Being heavily into HO, I really don't want to go out and buy a Marx book or guide just to find out more about this one item, so I thought I'd turn here. I have also joined a Marx Yahoo group and, if I strike out here, I'll be posting there as well. Already I have followed links in that group to the Thortrains site, where there is a nice history of Marx trains, even a little bit about my particular train, but I am hoping somebody here can tell me more. It's a Marx Mercury set in its original box, but it appears to have an additional car in the set as well as more track. There is a throttle pack and Marx rail-clip with two cloth-covered wires still attached. A lionel clip is included and that seems easier to attach to the track. The train itself is a copper color. The consist includes engine and tender, a mail/baggage car, a passenger car 'Chicago' and two 'Detroit' cars along with a streamlined observation. All have lights inside. The engine appears to have an E relay attached to the motor. There is no smoke or whistle unit, but there is a red gel plastic insert in the smokestack. The train appears to be in fair/good condition with a few chips & abrasions here and there. I've started checking ebay to see what auction prices there are running. I don't have any real intention to sell right away, I'd rather restore it and put it to work at Christmas around the tree. But I would like to know what it is worth (dollars). Thanks in advance for any help I receive. I'll get pictures up eventually.
