Thanks to everyone who replied, the replies I got will be very helpful! I am think of uploading photos of my HO locomotives............They are Bachmann, Tyco, Mantua, Life-Like, and AHM.

Hello everybody,
I am new to this forum and I have a question about starting a layout for HO scale trains. I have many trains in HO, brands including Bachmann, Mantua, Tyco, and Walthers. Expect I would like my layout to be 1970s themed, with materials made by companies back then. However, I understand that the older stuff less less quality, but I already have replaced crummy horn hook couplers and other things to make them better. But as far as they layout goes, I do need some help with at least getting started. I have several hobby shops nearby me that are very helpful, but i thought it would also be a good idea to try something different.
Thanks very much,
Sebastian Marconi
