There were ten versions of the L18's produced, each with individual variations in the lettering/owner. The main four are China Rail, Dalian North Liang Company Limited livery, Dalian Kuang Consolidated and Yingkou grain Company Limited. Some of these types have minor differences such as color in the lettering, with or without CNR logos, etc.
Physical details such as step ladders, brake wheels, handrails and ladders are really very nice. The under body hatches, although non-functional, are nicely reproduced. The roof walks are the only thing I really don't like about these cars. They are far too thick, and are unfortunately cast on as part of the main body shell, making removing them to replace with etched metal walkways near impossible. A few of my cars lost brake wheels and ladders soon after purchase. I checked some of my other cars and sure enough it appears that there is no glue holding the parts in place! All the lettering is beautifully applied and the metallic paint work is particularly nice with minimal 'grain'.
The cars have a nice weight and roll very freely. The deep wheel flanges don't like Peco code 83 turnouts, but I think we're all getting pretty used to these shenanigans.
Bachmann EZ mates can be replaces with Kadee #5 (standard), #58 (standard, scale head) or #158 (standard, scale head, whisker).
These modern cylindrical hoppers will fit right at home on most modern layouts in China.
