Make Way for Trains! Holding Back Earth Materials
Curricular MaterialsA Community-Connected Elementary Geotechnical Engineering UnitIn the “Make Way for Trains” unit (MWT), students explore key concepts of geotechnical engineering in the context of a train track expansion for the Massachusetts Bay Transportation Authority (MBTA): as railway corridors are widened, the sloping earth material surrounding the tracks must simultaneously support existing structures and not fall onto the tracks. Developed specifically for the Boston, Massachusetts, context, the unit begins with a look at how MBTA workers employ science and engineering for the geotechnical support for
