Just wondered if there are any instances of 'unusual' engines being used for Banking duties in the steam era? For example, I know pannier tanks were quite common in BR days, and the LMS and LNER obviously built dedicated locomotives for particular locations, but are there examples of say, a Coronation class or an A1 being used as bankers, or industrials borrowed to bank trains on the mainline or anything else out of the ordinary?
