Totally support this! 73s are an iconic sight to be seen in the Southeast. Often used on RHTT services and used on driver training. Southern use their 73 to run driver training services and to run too and from Lovers Walk depot and St Leonard’s Engineering. Would be a great addition.
Sold definitely on board for this, do love a 73, had at least 2 maybe 3 on the Dean Forrest Railway for a short time, might even still be around, bean awhile since my last visit.
