Old Coach Brake Coach shell

This product is based off of the "Old Coaches"/"Teak Coaches" frequently featured in the first season of Thomas the Tank Engine and Friends.  They are loosely based off of the GNR ‘Metropolitan’ carriage, no. 903.  There are slight differences between the 1st class and 3rd class composite coaches, but there seems to have been only one brake coach.  I have created chassis with seating for the first, third, and brake coaches.  I have also created a cheaper alternative with no seats.  Links for the chain and Bachmann variations of the chassis are included below.
