The structure and capabilities of the linac beam dynamics part of the PyORBIT code are presented. The PyORBIT is an open source code, a descendant of the original ORBIT code that was developed at the Spallation Neutron Source (SNS) for design, commissioning, and studies of the ring. The linac part was started 8 years ago to utilize PyORBIT classes and infrastructure for the SNS linac simulations. The PyORBIT linac model has its own lattice description that is necessary to include lattice elements significantly different from the PyORBIT ring elements. The most important among them are accelerating RF structures. The five different RF gap models recently implemented in PyORBIT are discussed. Some benchmarks of the PyORBIT with Parmila, the XAL Online Model, and TraceWin code are presented.
