Class 37

The only 'Tractor' never to pull a plow (only joking mate)

Yes the class 37 has certainly earned a place in the 'Loco hall of fame'.

The Most Sucessful STEAM LOCOMOTIVE WHEEL CONFIGURATION

[/URL][/IMG] In wheel arrangement, the most successful wheel arrangement is the 2-8-0. Just about every American railroad had at least one 2-8-0 on their roster.

What about the last surviving SP GS-4

 

[SD45T-2]

The German DB V200! One of the major early diesels in Germany.

By Far the most successful electric locomotive in the United States has to be the PRR GG1. Entered service in 1935, last one retired by New Jersey Transit in 1983

I would have to say 2 loco's, the class 43 (HST 125). Built from 1975 to 1982. Hold the Official Record for fastest diesel, and only a total of 4 have been scrapped. They were only built as a temporary loco, while the ATP was developed, but because the APT was a failure, they have stuck. The Australian XPT is HST derived.
The HST:


Another successful locomotive is the Class 55 Deltic, built from 1961 to 1962, withdrawn in 1982, there are 6 in preservation, and 1 is still in mainline freight use, by GBRf. It uses Napier-Deltic Naval engines. The 1 in use for freight is hauling EMU's for refurbishment, and it has to go the long way round, because it would set off tunnel smoke alarms.

K-4

 

[edh6]

The Ffestiniog Railway England locomotives. Four were built in 1863, with another two in 1867. There were 4 still in use when the line closed in 1946 and two have subsequently been restored, with a third due to enter the workshops for a full rebuild this winter. There can't be many other locomotives that have been working almost continually on the same line for (just) over 150 years.
