The Great Central Railway ran a two-day Gala entitled "The Last Gasp" over the weekend of Saturday and Sunday 18/19 November 2017 before the railway would become festooned with tinsel and coloured lights for the "Santa" season. The highlight was the launch of the reproduction Diesel Brake Tender which was to make its first public runs in the company of the Railway's "Peak" diesel on the Saturday and class 20 on the Sunday. The title "The Missing Link" refers to the fact that these vehicles became necessary in the late steam era as BR's announced policy of fitting all its freight wagons with continuous brakes had fallen by the wayside and its diesel locomotives had insufficient braking power to work them, especially mineral trains. The Diesel Brake Tender was created simply to double the braking capacity and thus provide a link between the old and the new. Here we see it at Quorn on the Sunday.
