The link below contains info on the first run of 'The Fish' as a u-boat including a photohttp://members.optusnet.com.au/~mercurytravel/notebook/230/notebook.htm
In case the link were to disappear, a summation:-
- Notes that "The Fish" is a well-known business train to the Blue Mountains, and that it became a stainless steel electric train on September 15, 1958
- It's departure from Sydney was farewelled by the NSW Railway Commissioner N McCusker along with top railway officers.
- The new train carries name boards at each end, consists of 8 cars (although other evidence confirms it as 9 car set - 4 and 5 cars respectively), with a first class car marshalled in each of the sets, having a total accommodation for 528 passengers. Gross weight of train 401 tons.
- Prior to service the new train made several trips to Katoomba and Mt Victoria for instruction of drivers. During these runs a special test was made to simulate emergency situations in event of a train failing and having to be pushed out of the section.
- For this, the train was brought to a stand on the 1 in 33 grade half-a-mile west of Valley Heights and an electric loco from that depot was then brought behind the train and pushed it into the up refuge at Springwood. The loco then ran around the train and then hauled it to Lawson, making all stops en route. The train then continued under its own power to Mt. Victoria
- Mentions the new train will continue this service until intro of new tmetable on Oct 26 1958. On that date 1 set, after arrival in Sydney on "The Fish", will be utilized during day run No 23 Passenger 8.50am from Sydney to Mt Victoria, returning from there at 11.31am and due back in Sydney at around 2pm. This set will then be coupled to the other 4-car set to form "The Fish" that evening.
