BachFarish may have announced these models, however they announced stuff for 2005 which has still to appear.
When Dapol announce a date for release they usually stick to it or even improve on the schedule. They obviously have more control over things than BachFarish.
If they can switch their production round in answer to BachFarish's "challenge" then from my point of view it can only be better for UK N gauge hopefully less (or no) duplication and a greater range to choose from; I just hope it results in the Dapol Maunsell stock coming sooner plus any other SR stock from either manufacturer, like a T9, 700, N15 King Arthur, Nelson, Schools ...........................
