Just in case you don’t monitor the Trains Forum or others:
I’m looking for a good roster-type photo of a late-model CPR 2-8-0 fitted with an Elesco feedwater heater, showing the feed water piping detail on the left hand side, from tender to pump to Elesco to boiler input check valve, and piping to cab gauges and valves. CPR 3716 would be an ideal subject.
Can anyone help?
Isambard,
Here’s the result using “CPR 2-8-0” in a keyword search at the Index of Magazines, just in case you didn’t do that specific search:
“CPR Consolidation no.3616” Canadian Railway Modeller, July/August 1991, page 12 ( 2-8-0, CPR, “HOPKIN, KEITH”, STEAM, ENGINE, LOCOMOTIVE, PROTOTYPE, CRM )
“A brass kitbash: CPR 3512 - the steamer in the lake” Railroad Model Craftsman, November 1994, page 73 Could be kitbashed from the MDC 2-8-0 ( 2-8-0, CPR, KITBASH, “MASON, HERB”, MDC, STEAM, “TURNER, ROBERT”, CONSTRUCTION, ENGINE, LOCOMOTIVE, RMC )
Don’t know if either article has the details for which you are looking.

Isambard,
Just did a Google search using “CPR 2-8-0 3716” as the search argument. Turns out that she is at Kettle Valley Steam Railway:

Possibly they can help you with the photos you are seeking. Some of the other hits that come up during that search might be of use. You’ll have to look and decide, eh.

Just to touch on the feedwater pump, what exactly do they do and how do they work? Are there different types, and also I noticed some steam engines do not have it located on top of the smokebox in front of the stack? Is it located elsewhere or is it something which came later in the design stage?
Thanks
Feedwater heaters were introduced by locomotive manufacturers in the mid 1920’s, as a means of using exhaust steam from the cylinders to pre-heat feedwater before injecting it into the boiler, thus increasing thermal/locomotive efficiency. Most road locomtives and some switchers were fitted with feedwater heaters when built, with many older locomotives being retroffited later.
There were a variety of types of feedwater heaters - Elesco, Worthington and Coffin were some, with different shapes, locations and plumbing designs.
The Elesco feedwater heater was usually a cylindrical unit mounted on top of the smoke box in front of the smoke stack, but in some locomotive designs was located internal to the smokebox. The feedwater flowed through a number of coils within the heater, the exhaust steam flowing over the coils before being returned to the tender to be recycled.
The feedwater pump, usually located on the left hand side was steam driven and pumped water obtained from the tender up through the feedwater heater and through a check valve into the boiler. The check valve was usually mounted close to the feedwater heater and on top of the boiler.
On the locomotive right hand side the second feedwater system usually remained unchanged, with a steam-powered aspirator-type injector sucking water from the tender connection and feeding the mixture of steam and water into the boiler through the right hand side check valve.
Thanks for the magazine references Bob. Yes, it occured to me last evening that I should contact Kettle Valley Railway, since 3716 has moved there.
