(erielack) Steam Generator Discussion



Recently there were some discussions regarding steam generators on EL
equipment. I have acquired a document that provides some information for
the later EL passenger equipment.  The document is titled " ERIE LACKAWANNA
DIESEL_ELECTRIC ROAD AND ROAD SWITCH LOCOMOTIVES". The document was
produced by "Office of Chief Mechanical Officer" - dated July 22, 1968. I
have listed the engines that are stated to have steam generators. I have
also added some additional information from my copy of The EL Locomotive
Diagram Book - Jan. 1973 Revision.


809-819      	E-8      	OK 4740 - 1950 Gals ** 
820-833	E-8		OK 4740 - 1950 Gals ** 
900-913&	RS-2		OK 4616 -  800 Gals   2 units  - #s not specified
950-954	RS-2		OK 4625 -  800 Gals	  Balance of the 17 units
914-933	RS-3		OK 4625 -  800 Gals *
1400-1404	GP-7		OK 4625 -  800 Gals
1405-1409	GP-7		OK 4625 - 1100 Gals

I understand that the OK 4xxx units are Clarkson Vapor Phase.

*  MY 1973 Locomotive Diagram Book indicates that 914 & 915 had Superheater
M-2 	steam generators.
** MY 1973 Locomotive Diagram Book indicates that 816 had an OK-4740 steam
generator and 821-825, 829-831 & 833 had Superheater M-2 steam generators.
The other engines had no steam generators by Jan. 1973.

These are the engines that I have any such information on. I cannot tell
from the Locomotive Diagram Book when or if the E-8 steam generators were
changed between 1968 and 1973. I assume that those without steam generators
had them removed in that time period.
There is consistency between the 1968 Document and the 1973 Locomotive
Diagram Book on the balance of the engines listed.

Hopefully this information will clarify more than muddy the situation for
those who are interested.
