Below are the P&S engine numbers including the later period

Bicentennial era names, numbers, and a cross reference list. 

When the P&S broke away from the P.S.& N. in 1917 they used

a fleet of former P.S.&N. steam locomotives in the 1 00 and 200 series

numbers.  Later on they added larger former Monon 2-8-2s in the 500 series

In last part of 1953 the P&S began receiving nine EMD SW9 switchers

numbers 231 to 239.  Beginning in the mid 1970s they were all repainted

red, white, and blue for the upcoming nation’s Bicentennial Celebration

and given numbers of significant dates as well as various names of

famous Americans as well as names and numbers related to firearms. 

Later on the names were removed. Note that the EMD SW9 was almost identical the SW1200’s and similar to other EMD switchers.  The P&S also added three GP7’s #10 #11 & #357. 10 and 11 were mostly blue with a red strip and white trim.
