Usually preferred for smaller yards. Used for major yards or busy sections.
Points in the route, overlap and isolation are operated individually prior to Signal clearance.
Points in the route overlap and isolation are operated automatically with the setting of route.
Minor Point group is used. Major Point group is used.
NWKR/RWKR are normally pickup. NWKR/RWKR are normally dropped, pick-up only when Sub Route and Overlap are set.
Difference between P.I & RRI

Before setting any point individually,
it shall be ensured that all relevant
U(R)S and OVZ2U(R)R are normal.
Point setting is done by concerned U(R)S,
OVZ2U(R)R. Locking provided at various
stages takes care of the same
Points in the route, overlap and isolation are operated individually before signal operation.
Setting of points in route, overlap, isolation and also clearing the signal is achieved by single operation of pressing the GN & UN buttons together.
Point chain group not used. Point chain group is used for auto operation of
point.
Difference between P.I & RRI

After individual setting of points,
locking of points for the route is
achieved through U(R)S and
OVZ2U(R)R
U(R)S and OVZ2U(R)R are meant for
operation of points; W(R)LR locks the point.
NWKR/RWKR required for AU(R)S
& BU(R)S Route section setting. Route Section A U(R)S and B U(R)S are used for operation of point, NWKR and RWKR proved in DUCR of Sub Route.

In case of RRI, NWKR and RWKR relays are normally drop. Hence to know the movement is initiated for Main line or For a diversion line Z1UR1 relay is used. o Z1UR1 is a Normally drop Relay.
o Front contact of this relay is for diversion line. o Back contact of this relay is used for straight line.
o Z1UR1 is named after the point number.

o Due to high inductance of WR Coil, caused by its initial pick up current surge, back e.m.f is generated causes a high current to be discharge through rectifier across it and to avoid interference of this current with other circuit WR back contact is included.
o WR Once picked up it will remain in pickup condition via R3 resistance, so the current consumption will be reduced.
