For those planning any dios with various plastic kit railway tracks, be warned, they all vary slightly. I'm trying to finish a dio with the Italeri AB40 railcar, at a level crossing with scratchbuilt signal box, as used in Yugoslavia. My obs are as follows -
Italeri track -
Inner gauge 40.5mm. Neat looking track, offset centre bolt. Med length sleepers. Rail length is shortest of the 3 types. Not enough of it to do much with, apart from static model.
RPM track -
Inner gauge - hard to keep at 40.5mm, as rails are soft plastic and bend easily, thus tricky to fix exactly onto the sleepers. Sleeper length is v short, being the shortest of all, but some Russian sleepers were so ! There is little leeway for error, esp as no template provided, apart from measurements on box art. No location holes for the clasps (shoes?), but includes separate bolt details (a pain to add). Rail length is medium of the 3 types.
Revell track -
Inner gauge - nearly 42.0mm, overwide for some other kit types, eg my AB40. Rails just slides between the 3 'nail' keepers on sleepers. Sleepers are longest of all. No bolts provided. A plastic ballast display template is provided to hold and alternate the sleepers, and set up exactly, but if used it's hard to get the sleepers out afterwards due to the tight fit. I could cut the track through the middle to narrow it, if made neat enough. Rail length is longest of the 3 types. Generally, the most impressive / longest / largest.
Dragon + Trumpeter track - none held, so no comments. All donations welcome !
I'm still unsure as to which track is best suited for which country. All advice welcome. Ian Sadler suggests the 3 pinned Revell track would be best for a Yugo diorama. Overall, none can be easily used with other tracks.
Awhile ago when DML released their s-p armored rail cars and rolling stock, and when I was busily cooking diorama ideas that never came to be, I purchased some sets of railroad track made by Ironside. If I recall correctly, there was a meter of track in each set. Ties (sleepers) were linked together by sprues to ensure correct spacing when rails were slid into place through the plates. The sets included some trackside signalling posts and some other miscellaneous stuff I cannot now remember (the sets are stowed in a closet at the other end of the house).
My recollection is that I liked the look of these better than the track sets incldued with the DML kits. My recollection, however, does not do much towards a valid comparison with your careful statistical record. Still, you might look for them.
Hope this helps a little.
