GRS Signal SA1 Head Only Kit: O Scale

From the catalogs of the General Railway Supply Company the SA1.

The Type SA Signal produces a powerful signal indication at a minimum of energy consumption due to its scientific optical construction. It is equipped with an elliptical reflector which uses approximately 80 per cent of light emitted by the concentrated filament lamp. All three indications are projected through one lens, therefore the beam of light is always in the engineman’s line of vision due to the unchanged location of the three indications. The following features have contributed largely to the rapid adoption of this signal since its introduction in February of 1927.

It is now being used by:

41 railroads in United States

5 railroads in Canada

6 railroads in Foreign Countries

Signal head only for adding heads to our SA1 full signal.

LED is NOT included as there could be many variations. We used a red/green Tony’s TTX Ultra Micro Bicolor LED, 0605 Red & Green, 4 Pack, with resistors from Tony’s Train Exchange.

• Many of our parts come with supports still attached, and will need to be carefully cut. We always recommend a good sprue cutter for this. We suggest wearing eye protection.
  
• Parts that have had their supports removed may have some small bumps where the supports were removed that will need to be sanded/filed off for a better fit.  When sanding we suggest using dust mask and wipe with a moist paper towel so particles don’t become airborne.
• ACC glue works well for all our resin parts. Parts take paint well after priming. We recommend Mr. Primer Surfacer 1000 or Tamiya Surface Primer, but any good thin primer will work. All parts come unpainted.
• Parts must be primed/painted if exposed to sunlight as the resins will continue to cure and may become brittle. Normal indoor florescent tubes and LED lighting should not be an issue.
• All parts come unpainted.
