Unit 3F: Shoes (3F.2) Railroad Indicator(s) 4.3.3 The student will explain why the interactions among particles involve a change in the energy system.

When building a railroad, one of the largest challenges is connecting the individual rails together. If the rails come apart, the trains will go off the track.

Produce liquid metal at the site of the track can be difficult. One suitable way is through a called the thermite reaction. It occurs between iron (III) oxide and aluminum and is initiated by a spark. Because the product is iron, it can be used to join two rail tracks together securely.
