Steam Soundz

Enginespecs (e-specs)

I love the sound improvements in TC3+ (and later) versions Trainz offer, which allowed for improved steam locomotive "chuff" sound effects (enginesounds).  But unfortunately, there seems to be almost total lack of e-specs (written for the new spec) that perform well, and nearly all of them suffer from excessive "hissing", due to the locomotive's safety valves popping off (with no way to avoid this happening).

In late 2012, I decided to write some Trainz e-specs of my own that allow for ways to avoid the lifting of the loco's safety valves. I released a couple of e-specs that can be found in the Late-2012 e-specs section, near the bottom of this  page. While these e-specs were an improvement, they still were hard to control. 

I will be releasing a series of Trainz e-specs during 2013 that offer improvements over the late-2012 e-specs.  These e-specs provide for a way to control boiler temperatures, which in turn will prevent the safety valves lifting. These e-specs are designed to be operated with coal levels below 100% (normally in the 60- to 70-percent coal level range) for those times when the locomotive will not be using a lot of steam, such as running on level or nearly-level track. When used to climb steep grades or other conditions that demand for lots of steam, these e-spec can be operated with coal levels up to 100% (or more). 


Examples

An example of using the USRA Light Mikado e-spec is available which includes a video and text description.

USRA Light 2-8-2 e-spec - Cab Driver Ver.


This e-spec was made specifically for driving steam locomotives in CAB MODE -- not recommended for DCC/AI use.  See http://steamsoundz.com/e-specs for instructions regarding coal levels to use when running locos with this e-spec, as it may require a different technique that what you're accustomed to to using. If these methods are followed you should have minimal problems with keeping the boiler temperatures under control and have minimal problems with safety valves lifting.
 
This is a TS2009/TS2010/TS12 steam enginespec (e-spec) designed for Ben Neal's USRA Light Mikado (2-8-2) locomotive that enables it to pull approximately the same number of cars pulled by the real 2-8-2s, e.g. about fifty 55 ton cars (plus caboose) on level track and up .5-percent grade. Braking capacity has been slightly increased to allow for better handling of l-o-n-g trains down steep grades.

USRA Light 2-8-2 e-spec - AI/DCC Version


Recommended _only_ for AI/DCC control. Use kuid:123250:100042 for use in Cab mode. See http://steamsoundz.com/e-specs for more info.
 
This e-spec was created for use with Ben Neal's USRA Light Mikado 2-8-2 steam locomotive. When driven under AI/DCC control, you should have minimal HISSING due to the safety valves of your locomotives popping off.

B-28-2 Shay Locomotive e-spec

 
TC3+/TS2009/TS2010/TS12 steam enginespec (e-spec) for Ben Neal's B-28-2 Shay locomotive. Top speed is about the same as the prototype, e.g. about 7 MPH. Designed to minimize H-I-S-S from safety valves lifting under DCC/AI control but performs well when driven in Cab mode. 
 
When using this e-spec, update Ben's Shay to TC3+ specs and also change the animation distance in Ben's Gilpin 2 bogey 3 to 1.1166, in order to hear the correct number of chuffs per driver revolution (12). For best results use with Steam Soundz: B-28-2 Shay.

USRA 2-8-8-2 e-spec


TS2009/TS2010/TS12 steam enginespec (e-spec) for Ben Neal's USRA 2-8-8-2 Mallet locomotive that enables it to pull approximately the same number of cars pulled by the real 2-8-8-2 Mallets, e.g. about ninety 55 ton cars (plus caboose) up .5-percent grade at about 8 MPH. Braking capacity has been slightly increased to allow for better handling of l-o-n-g trains down long grades.
