Track Alignment and Geometry

What defines the elevation of the track along the line, either rise (uphill), fall (downhill), or no change in elevation and consists of straight elements and vertical parabolic curves?

• Horizontal Alignment

• Vertical Alignment

• Superelevation Alignment

• All of the above

What is the formula of Versine?

What is the type of vertical curve that is applied when the change in track gradient comes from a higher gradient to a lower gradient?

• Sag Curve

• Reverse Curved

• Simple Curve

• Summit Curve

What is the measurement of standard gauge?

• > 1,435 mm

• = 1,435 mm

• < 1,435 mm

• = 1,000 mm

What is used to connect a straight track to a circular curve and is inserted before and after a curve to prevent abrupt change in lateral movement?

• Slacking Transition

• Transition Curve

• Geometric Transition

• Cant Transition

What is an imaginary line used to ensure that the path required for train movement is kept clear and no structure such as walls, columns, beams, cables, pipes, and signal posts should pass this gauge?

• Structure Gauge

• Rolling Stock Gauge

• Narrow Gauge

• Broad Gauge

What consists of a circular arc which has the same radius along its entire length, from one tangent track to another?

• Compound Curve

• Transition Curve

• Simple Curve

• Reversed Curve

What is the measurement of narrow gauge?

• > 1,435 mm

• = 1,435 mm

• < 1,435 mm

• = 1,000 mm

What is the formula of Railway Cant?

What is an imaginary line which indicates the space that a rolling stock may occupy, laterally or vertically, along its route?

• Structure Gauge

• Rolling Stock Gauge

• Narrow Gauge

• Broad Gauge
