Hi, A friends son has just had delivered this product, but they are still running analog at the moment, but will be looking to move to DCC. Will this run on an analog system still, and if so would you have to fit a blanking plug. Thanks in advance. https://uk.hornby.com/products/coronation-his-majesty-king-class-66-06523-king-charles-iii-club-exclusive-r30238txs
