Total Length of Crossover = Length of Curved Leads + Distance between Centers of the Tracks

Length of Curved Leads:
The length of the curved leads can be determined by calculating the arc length of the crossing tracks. Since the tracks are parallel and have equal angles of crossing, the arc length can be calculated using the formula:

Arc Length = (Angle of Crossing / 360) * 2 * π * Radius

In this case, the distance between the centers of the tracks is given as 7.35 m. Since the tracks are parallel, the radius of the curved leads is half of this distance, i.e., 7.35 / 2 = 3.675 m.

The angle of crossing is not given directly, but it can be determined using the properties of parallel lines and transversals. When two parallel lines are intersected by a transversal, the alternate interior angles are equal. In this case, the tracks are the parallel lines and the transversal is the crossover. Since the angles of crossing are equal, we can consider one of them. Let's assume the angle of crossing is θ.

Now, the arc length of the curved leads can be calculated as:

Arc Length = (θ / 360) * 2 * π * 3.675

Distance between Centers of the Tracks:
The distance between the centers of the tracks is given as 7.35 m.

Total Length of Crossover:
The total length of the crossover is the sum of the length of curved leads and the distance between the centers of the tracks.

Total Length of Crossover = Length of Curved Leads + Distance between Centers of the Tracks

Total Length of Crossover = (θ / 360) * 2 * π * 3.675 + 7.35

Given that the distance between the centers of the tracks is 7.35 m, we can solve for θ.

7.35 = (θ / 360) * 2 * π * 3.675 + 7.35

Simplifying the equation:

(θ / 360) * 2 * π * 3.675 = 0

θ = 0

Substituting the value of θ back into the equation for the total length of the crossover:

Total Length of Crossover = (0 / 360) * 2 * π * 3.675 + 7.35
= 0 + 7.35
= 7.35

Therefore, the correct answer is 7.35 m.

Given: D = 7.35 m and G = 2.35 m
