I'm debating with myself about track selection. My installation will be permanant - it does not have to be portable - and I would like the improved realism of track with separate roadbed instead of integrated. However, I understand that integrated track/roadbed systems (FastTrack and RealTrax) can have gravel imposed over it to enhance realism. It appears the choices are between MTH ScaleTrax, Gargraves, and Atlas, and possibly Ross (although when I've done a search on Ross trackage, I found nothing) for realistic trackage. Does anyone have pictures or sketches of cross-sections of these different tracks that can be shown side by side for comparison purposes? I know they all have their pros and cons? What are they? They probably fall into these categories: Material: Tin plated vs. nickel. Nickel makes magnetraction useless. But it looks good and wears well. Other issues? Variety of pieces available: For example, I want to be able to have curves as small as O-31, whereas FastTracks' tightest curve is O-36. Tie spacing: MTH's are further apart compared to Gargraves? Where does Atlas fall in this mix? Performance: It sounds like they are equally reliable, including switches Tubular vs. solid rails: MTH is solid. What are the others. What are the pros and cons? Center rail: Are they all thin to make it less prominent? I know MTH ScaleTrax is. How much of a concern is more rapid wear of the pickup rollers?. Overall appearance/realism: Matter of preference? Availability: Depends on where you are? How about internet availability? Atlas seems most available, followed by Gargraves. Price: ? About equal?
