Great British Railway Journeys
Welwyn Garden City to Peterborough
S8 E2:
Michael begins a new journey north from London, but he’s forced to expend more effort than usual as he pumps a track inspection trolley, then gets the chance to drive a 'locomobile'. He then goes back to school at Haileybury, where the master is unimpressed by Portillo's exam performance. Finally, Michael discovers a treasure trove of Victorian plant and soil samples.
