<h1>JMRI: LMS New Lines and Mirfield speed signals 1932-1988</h1>
|
|
This signal system contains signalling definitions for the LMS speed signalling systems
|
|
installed at Mirfield in Yorkshire and on the 'New Lines' in London, England in 1932 and
|
|
later modified in 1937 and 1959 before being replaced with conventional signalling in 1959
|
|
(Bow-Upminster), 1970 (Mirfield) and 1988 (Camden-Watford).
|
|
<p>The 1937 change involved extinguishing the lower red 'marker' lamp when the signal was not
|
|
showing stop implementing 1933 ministry of transport recommendations to standardise
|
|
signalling and the 1959 change removed the yellow over green advance caution aspect changing
|
|
it to an additional yellow over yellow bringing the aspects in to line with the rest of
|
|
BR.</p>
|
|
|
|
<p>Some extra aspect definitions have been provided for the signals that were not provided on
|
|
the prototype but might have been needed had the Mirfield system been extended or more widely
|
|
adopted.</p>
