Blue Pullman (single) sound decoder and speaker (21)
As there is very little authentic sound of the Blue Pullman on record, this project has been carefully created based on what can be regarded as the genuine, not dubbed recordings. The horns are produced to replicate the pitch and sound of the prototype, the F10 horn being a tribute to the double one heard on old archive footage. As this train ran primarily ran between London and Manchester the station announcements have been created using the correct departure timings for those stations, noting in the interest of authenticity, that in those days there was no such thing as a 24 clock announcement!!.
Pressing F2 and F3 horns at the same time plays both tones together, this practice was apparently used as by the driver as an emergency warning, pressing F2 and 3 together again stops the two horns. F19 is a 4 step volume control and mute, by repeated pressing of the function button the operator can set the level they wish, F21 is a fade up/down control which is set at 25% on fade down, useful for entering or leaving the display area of a layout, the minimum level can be changed by the operator by altering the value of CV133, values are 0 min 128 max, the default is set at 32 (25%).
Please note that this single sound version is not recommended for use in the Bachmann model. This is because both power cars are motorized, it is very difficult to synchronize the running of a sound and a non-sound decoder.
