...that
SNCF's Class BB 36000electric locomotives, built by
Alstom in the late 1990s, were originally a modification of an order for 264 of the dual voltage
SNCF Class BB 26000 but were instead built as a triple voltage design capable of also operating on 3kV DC with a different electric motor type (AC induction) and newer
power semiconductor device technology (GTO type)?
...that about half of the
stations on the
Moscow Metro in
Russia were built as shallow column stations with the distinguishing feature being an abundance of supplementary supports for the underground cavity following designs that employ metal columns or concrete and steel columns arranged in lines parallel to the long axis of the station?
...that like the
EMD DDM45, the GE BB40-9W, a
narrow gauge version of the
C40-9W, needed two more driving axles due to the limitations of the smaller
traction motors, but used four two-axle
trucks instead of the DDM45's two four-axle trucks?
...that with the introduction of the new
double-decker S-Bahn trains in the 1990s, the RABDe 12/12 class trains lost their prestigious role working the Golden Coast Express along
Lake Zurich where they had been used since the 1960s and were subsequently used on lines with low passenger frequencies, remaining in
S-Bahn service around
Zurich,
Switzerland, until 2008 with the last being scrapped in 2010?
...that Redfern railway station, which opened in 1874 south of the city centre in
Sydney,
Australia, was originally designed to be the principal station for Sydney, but was found to be too far from the city centre, so a new station (the present
Sydney Central Station) was built to the north and opened in 1906?
...that in the 17th and 18th centuries, before the advent of
steam locomotives, rails were fastened to
sleepers by pegs through holes in the rail, but as the flanged 'tee' rail was introduced in the 19th century, rail fastening systems evolved to use the various designs of spikes and spring clips that are now in use worldwide?
...that it is unknown how many people attended the
First Transcontinental Railroad completion ceremony at Promontory, Utah, on May 10, 1869, with estimates running from as low as 500 to as many as 3,000 government and railroad officials and track workers who were present to witness the event?
...that a pocket track, which is a section of
track that can be used to park trains, differs from a
passing loop in that the pocket track is usually located between two
main lines, rather than off to the side?
