Identical to <kuid:368725:35045>. Created for steam locos with 2 ash queues : a firebox queue, the primary location of ash accumulation, and an ashpan queue, where firebox ash is transfered by use of grate rockers prior to disposal.
With the advent of the TRS22 Properties editor, two queues with the same product were not displayed, and hence the need to differentiate the queue products for separate display.
