About us

PrimeKernel is an independent studio focused on the railway — faithful station interlocking simulators, and a dispatcher puzzle game for your phone. Instead of rough models we build on real regulations and real geometry.

Our goal is a simulator that holds up to a professional’s eye and still entertains an enthusiast — whether as a training tool for a centre or a single-player game.

Prime Rail Control, RailKernel and Clear Signal are products of PrimeKernel.
