Hi, Upon receiving my full rake of the new Mk3 Intercity coaches, I found that they were fitted with the electotren close coupling type and the buffers came withing the accessory bag. As a relative novice to coupling types, this may be a stupid question, but if I were to replace the couplings with the supplied tension lock couplings supposedly I would be able to fit the buffers and run the coaches on second radius curves? Also does anyone have any opinion as to how far to fit the buffers as the product images show them pushed all the way in so they are flush with the buffer beam, whereas Mk3 blueprints that I found show them in line with the gangway. If the latter will running be problematic with the tension lock coupling? Thanks very much.
