2.2.3. Reverse curves

Try these first

1. 1.

   What is the definition of a reverse curve?

   Hint

   Think about how they curve.

2. 2.

   Where are reverse curves primarily used?

   Hint

   Consider where trains commonly change direction.

3. 3.

   What characterizes a reverse curve?

   • Two arcs bending in the same direction
   • Two arcs bending in opposite directions
   • A straight line

   Hint

   Think about how they differ from simple curves.

4. 4.

   True or False: Reverse curves can be used on high-speed railways without issues.

   • True
   • False

   Hint

   Reflect on safety concerns.

5. 5.

   Design a reverse curve for a railway siding accommodating a train length of 400 meters. Calculate the radius required if the maximum speed limit is 30 km/h.

   Hint

   Remember to convert speed to meters per second.

6. 6.

   Critically evaluate the use of reverse curves in a proposed high-speed train route. What factors should influence their inclusion?

   Hint

   Think about speed, comfort, and safety in your analysis.
