NpB Track&Rail


NpB rail, G-scale track, and switches are 100% corrossion free and are the intelligent alternative to Stainless Steel.

Important Information to G-scale trackWe are often asked what track to choose. It all starts out with the question for the G-scale track height code 215, 250 or 332. Some argue that code 215/250 looks more prototypical. That actually depends. Modern standard rail would be correctly code 300 if it is to scale. But what is actually 100% to scale in our hobby? Not much and for some things there are very good reasons such as operational safety.

Code 332 rail gives you just that much clearance compared to code 250 or even code 215 rail. Very often we seem to forget that none of our rolling stock is weight wise to scale. Weight is the other very important factor that determines how you car will stay on track. I have noticed in my own layout that I have less problems with engines but more problems with cars derailing, and the difference is mostly weight. There is a reason why LGB choose 3mm wheel flanges over 1.5mm.

The next question is about material for G-scale track Aluminium/Brass/Nickel plated Brass/Stainless Steel/Nickel Silver.

 Aluminium is a very poor choice for track power, because its oxidizes within minutes

  • Brass is a very good conductor and oxidizes to a nice rust brown, however, needs to be regularly cleaned.
  • Nickel plated Brass (NpB) has the same excellent conductivity qualities of Brass but has a 100% corrosion free coating, that eliminates the daily grind of polishing the rials. Nickel plated Brass should not be mixed up with Nickel-Silver which has tendencies to oxidize heavily. Nickel plated Brass rivals Stainless steel which often shows pitting.
  • Nickel-Silver has good conductivity but only if it is not oxidized. I personally disliked all my Nickel-Silver pieces (some specialty switches and crossings) and I am happy that they are out of the layout.
  • Stainless Steel is with the exception of pitting corrosion free. But Stainless Steel has only 1/10 of the conductivity of Brass. In addition its price is of the charts in today's market so if you are looking for the effects of Stainless Steel pick Nickel plated Brass.
