Are there technical specs available for the whistle relay windings like there are for the motors? Specifically, the magnet wire diameter and turns used.
I am interested in published info, not measured.

In the Lionel Engineering Standards, section 38, there is data on coil WSR -46. Because of the abbreviation it is a little difficult to decipher.
A, taps, 0; B, turns, 1060; C, turns per layer, 65; D, winding length, (.?) 875; E, wire size, #29EN, F, wire required, blank; G, layer insulation, Glassine .0015; H, lead, “none but wire”; I, length of lead, 2”; J, Tube, “ .015 Manila .317 ID”; K, wrapper, “red G. K. .003”; L, sleeving, blank; M, resistance. 13 ohms; N, inductance, blank; O, treatment, blank. P, R, and S are dimensions on drawing 11. Drawing 11, on page 1, shows P as the coil length, 1.062” ; R is the OD, 0.875” max.; and S is the ID, .317” .
That is all I see on this coil.
That’s amazing. Who would ever have thought that much technical engineering went into our toy trains of years past.
Bob Hannon's O-Gauge Reference Manual I, Section 10, is on the relays - they all use the same coil and resembles the information above from @David Johnston
Rod,
I would.
Our Prewar toy trains were technologically advanced for the time. Folks today don't realize that toy trains were high tech in the 1930s and 1940s.

As Ed said, the engineering brilliance of Lionel, Flyer and Marx as well was amazing. Think of the "Vibrotor" drive on many of the Postwar Lionel accessories, which enabled them to cheaply produce things like the Sawmill and Culvert Unloader that would have needed AC motors otherwise.
And 60+ years later, they STILL WORK!
David Johnston, that is what I was after, thanks.
bmorin4, "Section 10, is on the relays - they all use the same coil"
Does that include the horn relays?
Dave
Yes, that includes the horn relays.
Thanks also.
Dave
