BR Class D16/1 LMS 10000
LMS No. 10000 and 10001 were the first mainline diesel locomotives built in Great Britain. They were built in association with English Electric by the London, Midland and Scottish Railway at its Derby Works, using an English Electric 1600hp diesel engine, generator and electrics.
Under British Railways the locomotives became British Railways Class D16/1; they were initially operated primarily on mainline express passenger services on former LMS lines, both in single and in multple. In 1953 they were transferred to the Southern Region for comparison with O. Bulleid's British Rail Class D16/2 diesel locomotives.
Both units were withdrawn and scrapped in the 1960s.

F6- Manual notch up [If CV155 is not 00]
F7- Manual notch down [If CV155 is not 00]
F8- Mute control [F8 to ON is muted]
F9- Brake squeal [Leave F9 on for auto brakes]
F10- User Sound [fan]

(C) General Notes The prime mover sounds for this project have been used from an early English Electric 16SVT 1600 hp Diesel Electic Unit and converted for 16 Bit sample use by the new author Barry T Gaskin

This is a rework of the project listed below, all credit to the orignal authors.
This rework has a reduced number of notch's and redefined functions to suit a UK locomotive better.
CV158 defines a driving style, if this is set to 0 (on) then the loco will notch up whenever the
Digitrax internal notch increases and decrease whenever the Digitrax notch increases. as there are
less playable notches than digitrax notchs this means that the loco can coast when decelerating
CV157 sets a maximum amount of time in seconds that the loco can coast for, after this time the
loco starts to resume the notch defined for the speed of the loco.
Playing Notch Digitrax Notch
4 6 - when you start to reduce the speed the notch reduces to allow the loco to coast
1 3 - speed held setady and loco continues to coast
2 3 - after the number of seconds set in CV 157 the loco starts to resume the actual power notch
This is a functional beta version of a project using individual sound recordings for each prime mover notch setting. These
prime mover sounds can be played in three modes determined by CV155: automatic, semi-automatic and manual notching. In auto
mode, the prime mover notch is determined by the current speed setting, and is adjustable using CV132. In semi-auto mode,
the same is true but it is possible to "throttle up" to higher notches using F6 and F7, if you want your engine to sound
like it is working harder. Manual mode offers full control of the notch setting using F6 and F7, so you can throttle down
to idle and turn on dynamic braking while coasting downgrade.
Other features available in this project include:
- Choice of 2 different horns
- Choice of 2 different bells
- Automatic grade crossing horn sequence with bell
- Optional highball and backup horn signals while stopped
- Dynamic brakes at speed, or handbrake while stopped
- Automatic coupler sounds when changing direction at low speeds
- Automatic brake squeal sounds when decelerating to a stop
- Additional user-defined sounds on F11 and F12
Using this project as a template, it would be simple to substitute your own sounds for the prime mover, horn, bell, etc. The
included sounds are appropriate for an EMD 2nd-generation 645 non-turbo prime mover, found in engines such as the following:

This sound project has been assembled from Digitrax-supplied sound clips as well as new sounds from custom recordings.
Additional engine and horn/bell sound clips courtesy of Matt Donnelly, recorded from various prototypes around the Northeast.
Thanks are due to Fred Miller, Bob Grosh, Jim Walton and A.J. Ireland for their prior work in developing sound projects.

With Digitrax Sound FX decoders and downloadable sound project files (.spj), you can download your choice of sound schemes into any Sound FX equipped locomotive. You can use spj’s that are available for free, you can modify those schemes or you can create your own!
Digitrax offers a wide variety of Sound FX decoders to fit many different locomotives. You’ll need to have a Digitrax SFX decoder installed to take advantage of using .spj files.Click here for Digitrax Sound FX decoders
