After seeing HST barrier coaches  6330 and 6338 with a pair of 20s on the GWML, I wanted to model them. So using an old Lima BG and Lima BSK progress had to start! I started off with the BG (6338) as it required less work to convert. I used the clear plastic your get from a kids toy packaging for window blanks. I also had to cut off some of the chassis details to get the prototypical look of the barrier coach. Taking the corridor connection off one end was time consuming but the outcome for a unique model is definitely worth it.
