Train, Ponton-. See [Pontons, Bridge Equipage].

Train-Bands (or more properly, Trained Bands). A force of militia, and not differing essentially from that force substituted by James I. for the old English Fyrd, or national militia. The train-bands of London were chiefly composed of apprentices; and their unruly doings formed the subject for many facetious plays and tales. In the civil wars, the train-bands sided with the Parliament; and Charles II. restored the militia on its old local footing.

Trajan’s Wall. A line of fortifications stretching across the Dobrudscha from Czernavoda, where the Danube bends northwards, to a point of the Black Sea coast near Kustendji. It consists of a double, and in some places a triple, line of ramparts of earth, from 834 to 11 feet in height on the average (though occasionally it attains an altitude of 1912 feet), bounded along its north side by a valley, which being generally marshy, and abounding in small lakes and pools, serves admirably the purpose of a fosse. During the war of 1854, Trajan’s wall became an important line of defense on the invasion of the Dobrudscha by the Russians, and the invaders were twice defeated in their attempts to pass it,—at Kostelli, (April 10), and Czernavoda (April 20-22).
