Prewar 072 locos?

[Anonymous]

I understand there were some Prewar ogauge locos that need 072 curves.  The scale Hudsons, Hiawatha, and M10000.  Are there any others?  Does the Flying Yankee or City of Denver need 072?

 Thanks,

the reference material I have states....

The Flying Yankee and City of Denver sets were listed as regular "O", not needing the larger diameter track.

A total list of prewar O72 Engines include....700E, 250E, 752W, 763E, 701 (1940), and the 226 (1941).

Hope this helps.

I don't believe the 226 was 072. It runs fine on my 031 and 042 loops.

Tim,

During it's 4 year run the 226 was always listed as an "O" gauge engine but became a crossover engine during it's last year of production in 1941.  If my information is correct it was also listed under the "072" catagory in set #293W at that time.  This is the reason I included it with other "072" locos even though it was originally listed as "O".  In those last years of Lionel's "O72" listings I'd guess they were shuffling engines a bit so that lonely T rail 700E's, 701's and 763's had another somewhat scale playmate.

P.S.  I recently purchased a 226E myself so I've been doing a bit of research.

The Prewar Lionel Flying Yankee (616) and Union Pacific "City of Denver" (636) Streamliners do not run on O-27 track.  Their minimum radius is O-31.  Now there was also a Prewar Lionel Union Pacific Speedliner (752W) that was for O-72 gauge only.  To keep the two separate, many refer to the smaller Union Pacific streamliner as the "City of Denver" set.  Otherwise, BRWEBSTER does correctly list the Prewar 072 locomotives.

Thanks Bruce!

 Any idea what the mimimum radias for the Flying Yankee and City of Denver sets are?

Smokebox,

Given that these are "O" gauge sets then they should negotiate 31" curves.   I could not say if they'd work on "O27" or not.

 The American Flyer 9900 Zephyr was a "wider" radius set,but I don't think 072.My Dad has one that's the diecast aluminium version.And it has a wide banked track it runs on.

 It's the older version that has something different in the way the motor mounts in the shell.

 Not 072 ,but it is a wide radius style engine worth mentioning.

Not sure but try this; if it has more than two driving wheels per side it may need a wider curve like 042.  042 might be a little less expensive than 072 and will allow for more common use on your layout than 072, 072 needs 8 sections for a half circle and 042 needs 4 or 6 sections for a half circle, depends who makes the 042 and when it was made as for 4 or 6 sections.

An easy way to find out is to take the engine in question to a layout that has several sized curves and see what the engine will accept without derailing.
