Victoria - Season 1 Episode 7 The Engine of Change

The queen becomes pregnant, and declares that Albert will become head of state in the event of her death. The developments outrage members of the Tory party, who fear a German prince holding sway over the nation and make arrangements to disrupt his visit to the industrial north. The consort finds an unlikely ally in Sir Robert Peel, who seeks royal approval for the rapidly developing railway. At first, Victoria does not approve, but soon changes her mind when she experiences Peel's creation for herself.
