I did not know that there was a cart called Emergncy +4

It was a cartoon, never saw it though.

I saw it a few times, when it first aired on NBC (1973-1976). Kevin Tighe and
Randolph Mantooth reprised their roles from the prime-time series. The premise: four children aided the paramedics of the Los Angeles County Fire
Department Rescue Division. It was produced by Fred Calvert and Universal.
I haven't seen it since, though.

I never saw it either

It was cute, but I like the original series better. :wave:

I remember when it was on but I never watched it.
