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.

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.

Siemens 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.
