I saw this (Collin Reinhart) photo of LRS 1421 on railcarphotos.com and thought maybe I could give modeling it a try. Obviously the boxcar has had it's height extended, but I found the added bracing on the vertical ribs interesting as well. Having the two different colours of green doesn't hurt either.I've cropped the original photo to remove items surrounding the boxcar.
Before you go though, here's a link to another YouTube video. This time it's highlighting Rapido's June 2021 arrivals (8 minutes long). Nothing there of interest to the JSSX really, but it's real good to see them continuing to add more to their product line.
