Techniques To Overcome Steep Hills
Some of the techniques that can be used to overcome steep hills include:
- dividing the load or splitting the train, which requires a siding at the summit.
- attaching additional banking engine(s).
- replacing the engine with a more powerful heavier engine for the duration of the steep grade.
- strengthening the track on or approaching the steep grade, allowing higher speeds, and allowing the train a run at the gradient.
- using two-in-one articulated locomotives such as the Fairlie, Garratt or Mallet locomotive.
- using a Booster engine, though this is usually limited to starting the heavy train.
- Zig Zags
- Spirals
- Horseshoe curves
- Rack railway
- Fell mountain railway system
- Elevators, cable railways, or funicular railways driven by stationary engines (cable haulage up and down inclines).
- Geared steam locomotives such as a Shay locomotive
- Atmospheric railway
- Cable car (railway)
- Rail surface treatment
- Compensation for curvature - the gradient is slightly eased on sharpest curves so that the tractive effort to pull the train is uniform.

“It is easy to lose confidence in our natural ability to raise children. The true techniques for raising children are simple: Be with them, play with them, talk to them. You are not squandering their time no matter what the latest child development books say about “purposeful play” and “cognitive learning skills.””
—Neil Kurshan (20th century)
“We can paint unrealistic pictures of the juggler—displaying her now as a problem-free paragon of glamour and now as a modern hag. Or we can see in the juggler a real person who strives to overcome the obstacles that nature and society put in her path and who does so with vigor and determination.”
—Faye J. Crosby (20th century)
“Summer involves going down as a steep flight of steps
To a narrow ledge over the water. Is this it, then,
This iron comfort, these reasonable taboos,
Or did you mean it when you stopped? And the face
Resembles yours, the one reflected in the water.”
—John Ashbery (b. 1927)
“The hills are alive with the sound of music.”
—Oscar Hammerstein II (1895–1960)
