This video from oorail.com is the first in our BR Eastern Region HST series. Follow along as we build a full British Rail Eastern Region HST rake between now and December. In this first part, we look at the new BR Blue and Grey Mk3 TS Coaches, these are equipped with interior lighting and you can see them running on the layout with our Hornby R2701 HST power cars. We also provide a quick comparison with the Western Region Mk3 coaches.
