Coast Douglas-fir is the second-tallest conifer in the world (after coast redwood), and the third-tallest of all trees, (after Eucalyptus regnans).Currently, coast Douglas-fir trees 60–75 metres (197–246 ft) or more in height and 1.5–2 metres (4.9–6.6 ft) in diameter are common in old growth stands, [4] and maximum heights of 100–120 metres (330–390 ft) and diameters up to 4.5–5. ...
A small circuit breaker typically has a manual control lever to switch the circuit off or reset a tripped breaker, while a larger unit may use a solenoid to trip the mechanism, and an electric motor to restore energy to springs (which rapidly separate contacts when the breaker is tripped).
A thermal switch (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint "plink" sound) and re-closes when the temperature drops. The thermal switch may be a bimetallic strip , often encased in a tubular glass bulb to protect it from dust or short circuit .

A Buchholz Relay is installed in the transformer oil circuit, and should the relay detect 'gassing' of the oil, will trip out the trains main circuit breaker, so isolating the equipment from the supply and therefore protecting the equipment from overheating or short circuiting.
