TO THE ED ITO R
TP&W SW1500s

Dear Mr. Lee: I recently picked up the April 1 99 1 issue of your magazine and thought I 'd send you some comments on it. I liked the TP&W S W l 500 information, and would like to add to the article. Herald King decal set L-430 is made specifically for this locomotive. I t includes the all-white striping a modeler needs to duplicate the prototype. Rather than mix Floqu i l or Scalecoat paints to obtain the vermil lion color, New Haven Socony Red could be substituted. It's close enough for all practical purposes. While on the subject of paint, the 305 was repainted by April 1 980. The white cab stripes were eliminated and larger Conrail-style numbers painted on the cab. The body striping and lettering on the long hood did not change. The yellow beacon light on the cab is not really necessary. All of TR&W' s SW l 500s were delivered without them. At some time, the railroad added them to the 304 and 305. They were removed sometime around 1980. Incidentally, the 304' s light was mounted at the front of the cab; the 305 ' s at the rear, as the photo shows. I question the location given for the photo; it sure looks like the building behind the 305 is the TP&W' s East Peoria, lL, headquar ters and not anything out at Galesburg. There are other paint and detail variations on the TP&W's four SW 1 500s . A special issue of the TP&W H i s torical Society ' s Prairie Marksman w as devoted t o these four units. Back issues of this edition are available. Alan Fricker, Editor Prairie Marksman Fargo, ND P.S. To switch to rear of the train, there are two N&W CF class cabooses still in existence. They are in DeKalb, IL, being used as offices. When I saw them in July 1 990, they were in excellent shape. Both were wearing bright red paint.

Reverse Loop Wiring

D ear Sir: I think that Mr. Ataras in his article (April ' 9 1 MRG) on layout wiring has missed Linn Westcott' s point when wiring a layout Keep It S imple. Most of us who have multi-cab, m u lti-block wiring have not had to resort to Mr. Ataras ' solution to his prob lem, because we do not have one common transformer for all cabs. Rather we buy or build cabs which have a transformer and a direc tion reverse switch built in (mine is a walk-around). Using sepa rate transformers allows you to reverse that cab's polarity to the mainline without affecting any other cab, because the only electri cal connection between the cabs is the common rail. (Remember each block has one cab at a time and neither side of any cab is per manently tied to the common.) The transformer allows each cab to float relative to the others. The floating reverse loops and floating cabs are connected to the common through one connection in the E/W switch. I have drawn a sketch for the wiring in the spirit of Linn West cott. The Direction (F/R) switch is normally part of the cab power pack and is an engineer function. The multi-pole E/W switch is a dispatcher function and can be changed to a two-pole switch. The normal/reverse entry (N/R) switch is a tower function (one per loop) and should be close to the reverse section, and it will be irrelevant which cab is using the loop. Note that if you use Twin T detectors in the reverse section they must be floating because either rail can be common. Allen Ferguson Winnipeg, Manitoba
