RAS Model Railway Sound Simulation
Simulators are analogue systems designed to simulate locomotive sounds and
synchronise them with the model locomotive type, speed and acceleration. They
differ from Digital Command Control (DCC) sound systems in the following ways:
· One system provides sound for all locomotives resulting in no per-locomotive cost
· A combination of under-baseboard and on-board speakers can be accommodated, giving greater volume and deeper tones from larger speakers, whilst providing localisation of sound with on-board speakers.
· By plugging into the track supply, a locomotive on that section of track will have sound simulated. Hence one system could be sufficient for a whole station or cab-control block, or more.
· Unless on-board sound is required, the locomotives do not need modification.
· Sounds are simulated, not pre-recorded and played back. Realism is created using methods such as reverberation.
· Distinction between locomotive sounds is possible using a special Remote Control Unit to pre-set up to 12 locomotive sounds.
· Other background sounds such as bird-song, a fireman shovelling coal, etc can be mixed in using an auxilliary input from a tape recorder.
simulator that you have heard is a prototype system and only four systems have
been produced so far. Custom-built systems are gradually being made
available to specific requirements and progress towards this goal can be
followed at this web-site or by asking to go on the mailing list by supplying

Firm quotations will only be supplied following
discussion of a specific customer’s requirements. However, the start-up cost
is likely to be around £150 for a ‘basic’ steam-only system, without
reverberation or pre-set locomotive settings. A steam/diesel combined system
will cost £190. A reverberation unit option (for a
realistic ‘echo’ effect) is likely to cost an additional £45, with the per-locomotive
Remote Control Unit adding an additional £100 for 6 locomotives or £130 for 12
locomotives. On-board sound will add another £40 and a 7W mono amplifier (for
use of the reverberation unit with passive speakers) approximately £15. The
customer will also need to purchase speakers.
