Historical Notes: The 38 Class ------------------------------------- Designed by NSWGR's Chief Design Engineer, Harold Young, during the 1930s, construction of the first five locomotives of the class by Clyde Engineering, Granville did not commence till the 40s and although hampered by the war effort, 3801 entered service in 1943. Featuring a cast steel chassis, boxpok drivers, roller bearings, 245lb boiler pressure, Franklin power reverse equipment it was always intended to be an "excitement" machine. The next twenty five locomotives were constructed in-house by the Railways and the last locomotive was running by September 1949. Due to high axle loadings, the locos were restricted to the Albury, Dubbo and Newcastle lines. Withdrawals commenced in 1961 and progressively locos were withdrawn and scrapped (due to a strong anti-steam attitude within the Railways at that time). Enthusiast pressure prevented the scrapping of 3801, 3820 was the last loco withdrawn in December 1970. Today only 3801 and 3830 are operational, 3820 exists at the NSW Railway Museum as a static exhibit and 3813 exists in pieces in various parts of the state.

MSTS Performance of 38 Class ------------------------------------------------------------ MSTS Performance - Notes by Don Martin I have designed the physics of this model to emulate the power,speed, and water and coal consumption of the prototype. Extensive reference has been made to sources of first hand information, especially the NSWGR Working Timetables, the ARHS "Compendium of New South Wales Steam Locomotives" edited by Alex Grunbach, John B Thompson's book for Eveleigh Press, "38", and articles in the ARHS Bulletin. In particular, users are referred to Bulletin number 525, of July 1981, which contains a number of logs of Flyer journeys behind 38 class locomotives. It provides a very useful comparison for your own journeys. To obtain accurate coal and water consumption from the tender, adjustments had to be made to the steam generation and usage figures. Unfortunately in MSTS the relationship between the steam generation/usage stats and actual consumption of coal and water from the tender is normally very poor. When prototypical steam generation/usage figures are used in an MSTS model there typically is an inappropriately small amount of coal and water consumed from the tender. Indeed, with the correct steam generation/usage figures for a 38 class entered into MSTS a fast journey from Sydney to Newcastle would use under 2,000 gallons, enabling the locomotive to return to Sydney, come back to Newcastle, and return to Sydney again, all on one tender. Of course, this is completely unrealistic. The present model instead adopts the more realistic goal of accurate tender consumption rather than reported steam generation/usage. In this model a fast journey to Newcastle will leave between 2,000 and 3,000 gallons, and 85% of the coal, in the tender. This is an accurate representations of reality as reported in first-hand accounts. In order to do this, the modelling has adjusted the reported steam generation usage figures artificially to create a much higher figure than users will be accustomed to. The figures are only nominal and are not meant to imply that a 38 class boiler produced such copious amounts of steam. It is purely a means of obtaining a practically more realistic performance. Driving follows the normal practice of ensuring steam usage does not exceed generation. The figures are simply higher than what users will be accustomed to. The relationship between steam consumption and generation figures is still important. As in the prototype, users will soon run out of steam if they try to run at high speed with a combination of high regulator and high cut-off setting. Consistent with the accurate water consumption is a high delivery of water to the boiler by the injectors. This has been set slightly higher than the NSWGR actual figures to reduce excessive injector noise in the cab. Note though, that the injectors do use a larger amount of steam to deliver the water than users may be accustomed to. Keep an eye on your steam usage when the fireman is injecting. He generally avoids injecting on ascents, and tries to keep it until descents, but on long, steep climbs when the engine is working hard, he will need to inject to keep the front tube plates covered. Sound - Notes by Don Martin I have created a sound set which is based on my own recordings of 38s in action. Unfortunately because the sounds are all genuine, it has not been possible to obtain sufficient range of sounds to ensure smooth transitions at the lower speeds. There are some very abrupt transitions at these lower speeds. Hopefully this lack of elegance will be outweighed by the "classic" sounds at higher speeds. I have found it a delight to run the journey from Sydney to Newcastle hauling a Flyer set, with my head out of the driver's window all the way. Very exhilarating with the sound turned up! The best recordings of a 38 class whistle I had was from 3820. That is the one that is used in this sound set. It is distinctively 38, but does differ from that which is on 3801. I hope you get as much enjoyment from the sounds as I have had over the long development and testing period. ============================================================
