And PRCo motorman's position Not Enclosed!!       But would like to know 
more about the basis for this decision before faulting PRCo.       *A*  
possible thought is that they don't want to  *sedate*  the motorman with 
heat which may cause an accident but just remove the chill in the area.

Another thought in this area  --  the 17s were designed immediately 
post-WW2 where the disciplines of rationing and sacrifice were still 
quite strong.

Not At All Surprized that PRCo had different heat settings for city and 
interurban cars  --  but Very Pleased to hear that they did.       Shows 
some very real thought on the part of the company, dispels this greedy 
attitude which is so often attributed to the companies, and also reveals 
attention to detail that we have already seen in the arena of 
safety.       This attention to detail seems to be spread quite wide in 
the company!

Excellent  Explanation  Below  --  really covers the various aspects of 
comfort which can be very relative.       Amazing how many people never 
put 2 + 2 together to get 21!!       People outside in winter come into 
thermostat controlled room, take off their coats, and complain about 
being too warm.       Within the hour of sitting to read the paper they 
are cold  --  same thermo room.       Slowing of circulation and the 
body furnace is Never Taken Into Account  --  has to be the room or 
something else!

Are ALL Euros so practical  --  or are You the Exception to the Rule?!?!
