Speed  *Seems*  slow but Down 6% grade sharing the track with 8 or 9 
other lines.......  --  weekdays midday in the latter 1950s 42-Dormont 
and 38-Mt.Lebanon headways were 15-min - other lines weren't far from 
that - headways every 20 to 24 minutes so it was not uncommon to have 
several cars in the tunnel at a time.     It can be difficult to judge 
how fast the car in front is slowing so a lower speed would allow 
greater time to stop.     Keeping the speed under control allows for 
greater safety margin Should Something Fail / air loss / whatever.     
In the early 1950s service on All Lines was Much More Frequent so it 
probably wasn't uncommon to have a half dozen cars in the tunnel Inbound 
at any one time.
.
Herb probably has much experience following TrolleyCars inbound in the 
tunnel, even though there weren't as many lines in the 1970s.

I always enjoyed the tunnel and remember one day very distinctly when I 
was coming home on the 42 on a 1601-city car  --  motorman had power 
about halfway depressed as we entered the tunnel and we leisurely 
climbed the grade.     When he put it on the floor it was Not Unlike a 
Pig stuck with a Hot Poker  --  *Seemed*  like the car was moving 
Considerably Faster with real thunder at each rail joint, breeze from 
open window, ozone wafting by  --  Wonderful Natural High~!~!~!~!~!
