well
for r1
use lgb coaches -as you like
they do all run on r1
rule 8
so what era is it that you are looking for?
marklin is re-releasing the smoothsides
the prices seem stupid compared to the old-inital street is about 400 each!!!!!!!!!!!!!!!
but
since i love passenger trains as well as freight-i dont always run era-i run whatever train i like-
i have set of smoothsides-(i dont model standard gauge or that era-but like many LGB items- i just had to have em anyway)
and they are wonderful-very smooth-well lighted-and while not looking too great while doing it they do run on r1 without a hitch
if you can find them on ebay they sell for less than the new ones, depending on roadname
using the same abandon for era or reality on my little line
worse still, aesthetically, are the amtrak coaches which are huge-i have run them on R1 and they will go but even to my undemanding eye-its a bit off-these are however, one of the most interesting and certainly unique offering from LGB
package deals on ebay are still around for amtrak items-engine and 3 cars for around 650US
