Do you have a picture of them all together? Those are actually the exact cars I was looking at before I posted this!Do you want what would be prototypical for the loco, or something that looks good?
I have the LGB/Aster live steam Frank S version and often run it with a longish string of LGB "train-set" coaches (red/white, blue/white) with the clerestory removed from the roof. Not prototypical but it does look good, and is a way putting cars which would otherwise not see much use.
Those look super nice!
Thank you, that's a really cool websiteSo N+FS is a pretty complex loco being built to 750mm gauge many of LGB offerings will be fine but not all. You need to keep away from HSB stock as this is from a Metre Gauge line, but as shown below having been in Austria for many years OBB Narrow Gauge Stock is fine as is Sachen stock DR though not truly prototypical if you read tge attached history.
