In Erie  practice, much of the automatic block and TCS territory used  
four-indication signaling, where the progression of indications on these  
intermediate signals was "Clear," (Green over Red); "Approach Medium,"  
(Yellow over Green); "Approach," (Yellow over Red); and "Stop and  
Proceed," (Red over Red).  "Approach Medium" had a dual  purpose.  It 
could govern the approach to any signal indicating  "Approach" or to an 
interlocking home signal indicating "Clear Medium" or  "Medium Approach."

And there was an exception to the rule................as always.
 
The EL Rule Book showed Rule 290--RESTRICTING to be displayed ONLY on  
interlocking or home signals.  This is indicated in the Rule Book by signal  
aspects in line above one another, not staggered, square ended semaphores, and  
no number plates on the signals.
 
Well, westbound at Meadville Yard, signal 516-1 at MP 103.39 was equipped  
to display a RESTRICTING indication when the switches were open into 
Meadville  West Yard.  This allowed the switches to remain open between trains 
and/or  allowed a yard crew to leave the switches open for the next train to 
pull into  the yard without stopping to line the route and tie up the road 
crossings in  downtown Meadville.  This was a two-arm signal with staggered 
heads,  and was equipped with a number plate (516-1).  It could display Clear,  
Approach, Approach-Medium, Stop and Proceed, and Restricting.  
 
When the Conrail rules guys showed up in 1976 looking the property over and 
 saw that they were lost for words.  It wasn't in the rule book and it  
wasn't in the EMP TT.  It ended up in the Conrail EMP TT as a Special  
Instruction post haste.  The Central Region Manager of Operating Rules, J P  McCombs 
just happened to be there when a train was lined into the yard and  
discovered it.
