How do locomotives know where they're going?
Why this joke works
Locomotives Get Lots of Training
Training is the process of learning skills or preparing for a task. A locomotive also belongs to a train, the connected series of rail vehicles it pulls. Saying locomotives know where to go because of “lots of training” credits education while hiding the vehicle word inside the activity. The plural “lots” suggests extensive practice, but it can also evoke the many train journeys and routes that produce that knowledge.
A closer look
The Route Knowledge Comes From Professional Education
The question gives locomotives independent awareness, as though the machine must study its destination. “Training” answers with both repeated education and the activity of being made into a train-related professional. The plural “lots” exaggerates the preparation and supplies a satisfying rhythm. Tracks still guide the imagined locomotive physically, while the punchline gives it the confidence of a qualified operator.
Fact behind the joke
Locomotive Engineers Must Be Trained and Certified
Federal Railroad Administration rules require railroads to maintain qualification and certification programs for locomotive engineers, with separate federal requirements also covering conductors. FRA audits those programs and reviews training, testing, monitoring, and certification practices. A locomotive itself follows rails, signals, switches, and human or automated controls; the trained person in the cab is responsible for operating it safely along an authorized route.
