Amazing Railway Adventures with Nick Knowles Series 2: Episode Guide & Ratings

Nick kicks off a new series, taking in three capitals: Prague in the Czech Republic, Bratislava in Slovakia, and Budapest in Hungary, with a climb and a cruise.

Nick names this trip "The Volcano Express". He travels from Mount Vesuvius to Mount Etna on a journey from Naples to Sicily, where a gyrocopter trip goes wrong.

The presenter tours Romania, undertaking a journey he calls 'The Transylvania Express'. He begins in Cluj-Napoca, taking a train to the disused salt mine of Salina Turda, where the vast underground cavern has surprising new uses. Nick also pays a visit to Romania's top tourist attraction, Bran Castle, the inspiration behind Bram Stoker's classic novel, Dracula.

In Morocco, Nick explores the old medina in capital Rabat; the city of Salé, where he finds out about its piratical past; and takes a tranquil dawn balloon flight.
