Terry Pratchett references I have got thanks to Well There's Your Problem podcast (about engineering disasters, with slides):
The Breccia pork futures warehouse in Men at Arms /Thud! probably refers to bonded warehouses and using warehouse receipts for nonexistent stock as currency, most specifically the Tino de Angelis salad oil fraud
Vetinari disguising himself as an engine stoker in Raising Steam calls back to Lenin using the same method to escape from then re-infiltrate St Petersburg before kicking off the Bolshevik Revolution.
