In what way were they the glory days? Initially, the nationalised system was run down after the war and saddled with the debt from buying it. The modernisation plan was a missed opportunity with too many types of often ineffective traction brought into service. A period of significant cuts and closures followed and the cash strapped 70s and 80s were hardly glorious. All the while BR lost passenger and freight business hand over fist. BR did some things well, such as Intercity, but this really was a time of managed decline rather than glory days.
