Reminds me of the frequent track fires on the old 3d Avenue EL along Webster Avenue...usually a Signal 5-7 (1 and 1)...but sometimes just a 5-35xx (E79 loved that easy booster line on their ‘51 WLF to put ‘em out)…and sometimes just 7-35xx if the Engine was out elsewhere...L37 would hook up the 50 foot length of inch and a half they carried, directly to the hydrant … enough pressure to reach the 3 storey’s height from the street to the tracks. Sometimes raised the wooden aerial, sometimes not... fun to watch as a kid.
