1. Give the history and development of model railroading.

2. Tell the difference in how the following prototype motive power units operate:

a. Steam

b. Diesel

c. Electric

3. Know the name, scale, and track gauge for four model railroad gauges.

4. Know the shapes and names of at least eight track plan arrangements.

5. Know at least six points to check for the maintenance of a model railroading layout.

6. Identify and explain the use of:

a. Five types of freight cars

Covered Hopper

Structurally, a covered hopper is very similar to an opentop hopper car. What distinguishes this type of car from an open hopper is the car's roof, and also the car's overall size. Covered hoppers typically carry loads of less dense, and therefore lighter, materials, so they are built to a higher cubic capacity than open top hoppers.
