BradfordLass72; Apologies for this if I've got it wrong, but aren't you in NZ? I thought I'd emailed about a prog. on SBS TV this Sunday,27/1, on the above subject. Follows similar progs in OZ about the Ghan and the Indian Pacific. I could be having a complete brain-fade with this heat!
Wasn't sure if NZ gets SBS, but if not, then again, apologies!
What gives you a warm feeling? 🥰
