Definetley know the show Touhy.
I saw some of it in the 70s when I was a little boy in Pennsylvania,the fire trucks were "neat" of course and the action.
I didn't see it again after the 70s until 1998!

I saw an episode on cable at someones house. Next time was just this past March,on the Retro TV Netwrok. Locally in Phoenix that is digital channel 3.2 KTVK.
I was babysitting for a friend 3 days in a row while her daughter elementary school was on Spring break. Along with Emergency,also saw Marcus Welby-The Bold Ones-Rockford Files-Adam 12-Dragent and Quincy.
Emergency is available on DVD,be good show to buy.
