Operation: Locomotive

Operation: Locomotive was a virtual representation of one of Jacob and Evie Frye's genetic memories, relived by a Helix initiate through the Helix Navigator.

Description
Queen Victoria tasked Jacob or Evie with learning the motives of the captured Templar leader.

Dialogue
Jacob or Evie met the Queen at Buckingham Palace. Jacob or Evie traveled to where the Templar leader was being held and fought him. Jacob or Evie raced to the train and located the bomb behind a locked door. Jacob or Evie detached the locomotive, allowing the bomb to detonate without harming the civilians.
 * Queen Victoria: Mr. Fleming has attempted to force a confession from your prisoner. The miscreant refuses to talk. Will you speak to the villain and learn his secrets?
 * Jacob: Oh, I'd be delighted, ma'am.
 * Evie: Leave it to me, your majesty.
 * Jacob: I don't suppose you'd like to spare yourself a tremendous beating and make a clean breast of it?
 * Evie: Must I pummel you severely about the head and shoulders? Or can we simply talk?
 * Templar: Might as well. The order was to load a train with explosives at Westminster. It'll detonate before reaching Southwark station and kill everyone aboard!
 * Jacob: I did not expect you to confess! Which train?
 * Evie: You people and your damned dynamite. When does it happen?
 * Templar: It's the next train! It should leave at any moment! You'll never make it in time!
 * Jacob: Damn! I can't reach the bomb. I'll detach the locomotive.
 * Evie: Locked! I'll separate the bomb from the other cars!

Outcome
Jacob or Evie prevented a dynamite explosion from killing a train of civilians.
