Young Curly Blonde Girl Changes The Railroad Switch On The Railway Track

• Wye switch
A wye switch (Y points) has trailing ends which diverge symmetrically and in opposite directions. The name originates from the similarity of their shape to that of the letter Y. Wye switches are usually used where space is at a premium. In North America this is also called an "Equilateral Switch" or "Equilateral Turnout".Common switches are more often associated with mainline speeds, whereas wye switches are generally low-speed yard switches.
• Run-off points
Run-off points are used to protect main lines from stray or runaway railroad cars or from trains passing signals set at danger. In these cases, vehicles would otherwise roll onto and obstruct a main line (sometimes known as fouling) and cause an accident. Depending on the situation in which they are used, run-off points are referred to either as trap points or catch points. Derailers are another device used for the same purpose.
