The Connecticut Trolley Museum, also known as the Warehouse Point Trolley Museum, is the oldest incorporated museum dedicated to electric railroading in the United States. Founded in October 1940, the museum is located in East Windsor, Connecticut and is open to the public February through December. The museum features static and moving displays, and self-guided tours of the state's trolley history.

Grains may be lost in the pre-harvest, harvest, and post-harvest stages. Pre-harvest losses occur before the process of harvesting begins, and may be due to insects, weeds, and rusts. Harvest losses occur between the beginning and completion of harvesting, and are primarily caused by losses due to shattering. Post-harvest losses occur between harvest and the moment of human consumption. They include on-farm losses, such as when grain is threshed, winnowed, and dried. Other on-farm losses include inadequate harvesting time, climatic conditions, practices applied at harvest and handling, and challenges in marketing produce. Significant losses are caused by inadequate storage conditions as well as decisions made at earlier stages of the supply chain, including transportation, storage, and processing, which predispose products to a shorter shelf life.
