On my RR Hall, Olton Hall, the loco chassis did have brake gear fitted and yes you are correct, no brake rodding. This however was easily remedied by purchasing the main range accessory pack from Peters Spares. Despite this being a RR model, even the Scotsman in this range has these features. I would be very suprised if Hornby release this loco without this level of detail, they have otherwise gone to a lot of trouble fitting both sprung buffers and a 5 pole motor which doesn't add up.
Perhaps this is why production of this loco has been delayed ?????
