Automatic switchers

[NW Mailing List]

 If I remember correctly, there were automatic controls of the boiler water, the draft fan (and maybe the firing rate) so that the boiler could be kept hot while unattended. Only the 1100 and 1112 were "automatic".

 What was automatic about the Automatic Switchers in steam...?
Were there other than 4-8-0s?
