How come that both the locomotive pair and Cafe power car inform us (both on-line and in the catalogues) that "Modelers can now accurately duplicate Amtrak's standard eight-car Acela® consist by adding to the Spectrum® Acela® Express train set, or by building their train one car at a time." whereas catalogue numbers 89972, 89973 & 89974 do not appear anywhere I can see? 

In 2010 catalogue, Item #42523, 26 piece Graduated Trestle Set: says "not compatible with E-Z track" - Are there 13 pairs of different pieces? What actual heights are the trestles? May Atlas track usable? May Atlas track be used in Items #46904 Blinking Bridge and #46905 Bridge?
Are Items #46721 Blinking Bridge & Trestle and #46723 Bridge & Trestle (as in 2008 catalogue) still available? If not, what similar parts may be used not on E-Z track? Do you know of a dealer where I can buy them? (They are not available in New Zealand.)
