Ratio made both as I recall. The problem was the lack of gauge-widening on our tight model curves. We used P4 bases on curves on our EM layout! The P4 bases are OK on straight track but that's about it.@WM183
Hello
Be wary of Ratio P4 track bases - they pop up sometimes on EBay. I seem to recall discussions that they are actually EM.
