948707 Class 46 97403 Ixion RTC Blue/Red With Sealed Beam Headlights Diesel Locomotive - DCC SoundIn much the same way as the locos were produced in real life, the development of our N Gauge Class 45 and 46 has progressed as a continuation from the Class 44. To streamline the process and save time in production, we included the research, development, and tooling for all three classes when we began development of the Class 44s. This gave us the freedom to announce the arrival of these locos somewhat sooner than we would have done for other models
