GWR 48xx with Autotrailer’s
(Both sounds in the locomotive)
GWR 48XX
Built from 1932-1936 these Collet designed 0-4-2 Side Tanks were designed for light branch work.
Originally numbered in the 4800-4874 series the locomotives were renumbered to 1400-1474 in 1946 to allow for 2-8-0 locomotives fitted for oil burning to be allocated the numbers.
These small tank locomotives could could be found scattered as far as Birkenhead, Fishguard, London, Weymouth and Ashburton.
A similar class the 58XX (numbers 5800-5819) identical in every respect apart from not being autotrain fitted.
BR number series 1400-1474 (Renumbered in 1946 by the GWR from 4800-4874)
Last locomotive withdrawn 1964,.

The GWR 48xx sounds have been recorded from the prototype.
The principle of autotrain working is briefly having a driving cab in a coach allowing the driver to control basic driving functions remotely.
The operation of autotrains dispensed with the need to run the locomotive around to the other end of the train at terminating points of the trains journey.
When driven from the autotrailer cab the driver had control of the regulator, could set the brakes, and had a warning gong.
Trailers were also fitted with AWS (Automatic Warning System bell and horn).
There was also a handbrake and buzzer or bell system to communicate with the fireman(who remained on the locomotive) and the guard.
At Wheeltappers we have developed a locomotive decoder that complements the autotrailer.
This is a cheeper version, rather than having a sound decoder in the locomotive and another in the autotrailer, this version only has one decoder to be fitted in the locomotives bunker.
The decoder has been developed to use 1 or 2 autotrailer’s plus normal mode.
Please read the information sheet provided.
The whistles/gongs will work directionally with the sound emitting from the Locomotive only.
Lighting and oil lamps for the autotrailer can be worked from a separate function only decoder but will require separates pickups from the autotrailer.
Some sounds have been enhanced with archived sounds.
Please choose carefully which decoder type.
****Note****
‘O’ Gauge has different settings.
Please choose carefully which decoder type.
