Tender (rail) - Tender Design Variants

Tender Design Variants

In the early days of railroading, tenders were rectangular boxes, with a bunker for coal or wood surrounded by a U-shaped water jacket. This form was retained up to the end of steam on many coal-burning engines. Oil-burning engines substituted a fuel tank for the bunker. Variations on this plan were made for operational reasons, in attempts to economize on structure.

Famous quotes containing the words tender, design and/or variants:

    Farewell? a long farewell to all my greatness.
    This is the state of man; today he puts forth
    The tender leaves of hopes, tomorrow blossoms,
    And bears his blushing honors thick upon him:
    The third day comes a frost, a killing frost,
    And when he thinks, good easy man, full surely
    His greatness is a-ripening, nips his root,
    And then he falls as I do.
    William Shakespeare (1564–1616)

    A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.
    Freeman Dyson (b. 1923)

    Nationalist pride, like other variants of pride, can be a substitute for self-respect.
    Eric Hoffer (1902–1983)
