Rather than creating it's own thread, this post is dedicated to the first electric loco in NSW, the locally built 7100 (originally 4501). I'll make a post for it with the rest of the 46's on the first page with particular details. In it's green and gold livery it was affectionately known as the "Green Beetle", although I read that in it's later years, with various failures it was apparently known as "Nervous Nelly".
Wikipedia Info:- https://en.wikipedia.org/wiki/New_South_Wales_45_(later_71)_class_locomotive
A few notable things from the Wikipedia posting of it's duties included:-
- Used mostly in Sydney metro area to assist goods trains between Strathfield Hornsby
- Used to test new sections of overhead west of Penrith.
It's worth noting at the time of it being completed and into service in July 1952 the electrified network was fairly limited.
The following is the loco's listing on the State Heritage Register:- http://www.environment.nsw.gov.au/heritageapp/ViewHeritageItemDetails.aspx?ID=4807248
A couple of notes of interest from the register information:-
- 7100 was constructed utilising components common with suburban electric rolling stock, indicating a level of care to ensure there would not be a proliferation of spare parts for different vehicles
- The locomotive had it's first opportunity to haul passenger trains once electrification reached Penrith in October 1955
- It was assigned to Flemington electric car sheds in the early 1960's where it was used to shunt and marshal long distance loco hauled air-conditioned trains which were maintained at this depot and as such renumbered into the shunting loco series as 7100 on 20 October 1961. While also freeing up the 45 number for the new 45 class diesel-electric locomotives.
- It was withdrawn in 1965 due to increasingly regular mechanical problems and sat idle for 3 years.
- It was overhauled in 1968 and fitted with external equipment doors and several tonnes of additional ballast and repainted Indian Red with yellow lining for use on the newly opened Glenlee electrification for hauling coal trains from Glenlee to Rozelle coal loader, commencing duties in May 1968.
- It's non-standard design, failures in service and lack of equipment compatability with the 46 class saw it withdrawn from service after traction motor failure on 10 February 1969
- It was stored at DELEC awaiting repairs which never came and it was written off in October 1974
- It was subsequently transferred to the RTM at Enfield before being relocated to Thirlmere.
- With the RTM relocating from Enfield to Thirlmere, it was hauled there with steam loco 2606. Both of these were hauled by recently restored steam locomotive 3526 which was then itself withdrawn (wikipedia info for 3526)
- The loco was a museum exhibit at the NSWRM until it was transferred by rail to Broadmeadow in late 2008.
In terms of it's mechanical state, it seems it is missing quite a few key components that were likely removed before it was handed over to the (then) RTM for preservation.
- The 6 bogie mounted traction motors have been removed
- All electrical power systems are inoperable due to missing components including switchgear and the 6 bogie mounted traction motors
- drivers control stand and electrical gauge panels have missing fittings, loose wiring and open cabinets
- High tension cabinets have been stripped of the majority of their electrical components
- The locomotive's air compressor is missing
Some interesting information on the NLA Trove
1952, July 2. "Rail Test for New Locomotive"
- Notes that the first electric locomotive constructed for the NSW Railways will undergo special trials today.
- Engineers expect it to outstrip the all-round performance of the largest steam locomotives in service and more than equal the performance of 2 double-coupled diesel-electric locomotives
- Notes the order for 40 46 class electric locos for the (then planned) Sydney - Wallerawang electrification.
- Notes the trial run for the loco will go from Flemington to Wynyard; Wynyard to Strathfield, then Hornsby and return via North Sydney to Flemington.
- There will be a speed test between North Strathfield Junction and West Ryde and the locomotive is expected to eexceed 70 mph.
- Notes the locomotive was designed by NSW Railway Engineers.
- Construction of the loco began in 1949, but difficulties made it necessary for the department to enlist outside assitance.
- A number of firms helped and certain machine work was done by Garden Island Naval Dockyard
- Australian General Electric supplied electrical equipment and assembly and wiring were done at the department's Chullora Workshops
- The running weight of the locomotive is 112 tons - less than half the weight of the powerful D57 and D58 Steam locomotives, but it will haul the same load at a faster speed.
- For passenger traffic the locomotive will haul a heavier load at a faster speed than the modern C38 express steam locomotive.
- Commenting yesterday on the trial of the electric locomotive, Minister for Transport W H Sheahan said "Electric traction willl play an ever-increasing part in railway transport. But for the war, plans to provide more extensive electric train services would have been in operation today"
- He also mentioned that the public could look forward to electric trains operating as far as Wallerawang in the west; Goulburn n the south; Newcastle in the north and Port Kembla on the South Coast.

July 3, 1952. LOCO DOES 75 MPH. Trial Runs Impress.
- Notes that the locomotive travelled at 75 mph for more than a mile in the July 2 trials.
- From a standard start at Strathfield station the locomotive covered 7 miles to West Ryde in 7 minutes
- Jammed into the 2 driving compartments were various officials including the Railways Commissioner Keith Fraser, Chief Electric Engineer R W Mackay among 2 dozen + senior railway officials.
- The locomotive has 6 motors, each generating 450 amp and is at present the most powerful railway unit in Australasia.
- Notes that the 40 46 class electrics will be 1000HP more powerful
- Notes the trial was from Wynyard to Hornsby via Strathfield and return by the North Shore Line.
- The new locomotive was frequently stopped because it was getting ahead of strict track schedule.
- After further trials it will haul carriages on the Wynyard-Liverpool service.
- The new locomotive was designed by engineer R J Burn and constructed in Chullora Workshops

July 3, 1952. Schoolboys are still interested in engines.
- Notes that with the new electric locomotive trialled yesterday, hundreds of youngsters many with cameras were at all the vantage points along the route.
- Notes that had the railways suspected this they might have made the trial outside school hours.
- The loco didn't start it's run until 9:40am and as such many of the boys must have been late for school!

July 3, 1952. ELECTRIC LOCO IN HIGH SPEED TEST.
- Notes the the loco reached 75 mph in a speed trial
- The speed test was made between North Strathfield Junction and West Ryde.
- The locomotive is to be used on the western line when electrification is completed
- From a standing start the locomotive reached 60 mph in less than 400 yards
- People standing on the platforms and near the railway line ran to get a glimpse of the green and gold locomotive as it flashed past, followed by a trail of dust.
- The loco made it's trial run from Flemington to Wynyard, Wynyard to Strathfield, Hornsby and return via the Harbour Bridge to Flemington.
- When railway engineers stepped from the locomotive at Hornsby they said it exceeded expectations.
- The Commissioner for Railways who travelled on board the locomotive said the trial run was 100% successful.

Sydney Tramway Museum's December 1980 Trolley Wire Issue
- Notes that there was a celebration by the SRA for 125 years of railway operations in NSW with displays at Sydney Terminal on weekends from 27 September to 19 October 1980.
- The issue states that the display was rather disappointing in terms of the collection of rollingstock and locomotives on show, which were alongside platforms 8 and 9.
- The sole electric representative was locomotive 8510
- It notes that only 1 electric vehicle was present for the 100 year celebrations in 1955 and that was locomotive 7100 (then 4501)
