Frog Bolt: A "frog bolt" is a type of bolt used in railway track work. It's specifically used in rail joints where two rail sections meet. Rail joints are necessary because rails are often manufactured in shorter lengths and need to be connected to create longer track sections. Frog bolts help secure the rails together at the joint, ensuring stability and proper alignment.
