PERUMKA lias a n cstc~isivc railway nclivork in Ja\rii but most of tlic signalling is still mcclianical and up to sixty years old. Over tllc last t~~cn ty - f i \~c ycirrs rcl;ly intcrlockings li;r\c bec~i installed ;]I thc larger stations to increase oper;iting cfficicncy.

After the contract was signed a consultant was ellgaged to review the proposed system and it was believed it would be difficult to achieve the desired spcc~ficatio~~. At this time ANSA Comnlunicatiolls of Queensland (now AWA) had developed a multiplcsi~rg systcni using optical fibre cable as a bearer specifically for applications such as rail\vays. This had considerabl~~ reduced the cost of drop and inserl tcr~ninals illid tlic option of an optical fibre bcarcr cablc was priced ; ~ n d corl~pared to the previous proposal. Althougl~ tllc optical fibre cablc optiotl was still Illore espcnsrve it ~vas guaranteed to pro~.idc acceptable p c r f o r ~ ~ ~ a ~ ~ c c i ~ n d avoided potential risks associated w ~ t h t l ~ c coppcr bearer s! stem

Ilntil this project PERUMKA had had IIO cspcricllcc of using optical fibre cablc arid thus this option ~ ~ o n l d involve tllc supply of considerable rest and joinling equipment 2nd staff training. As another ofCsct PERUMKA wonld gain a co~nmunic;~tio~is sj'stc~n that could p ro~ idc mu cl^ greater bandwidtll for fi~turc capacity.

It is of course still up to the level crossi~ig keeper to operate the alarnis when the train is approaching the crossing based on his particular local knowledge.

Tlrcre are existing Sic~nens gcogrophical relay i~~terlockings at Cirebo~i and Yogyakarta. WSA be installing axle counter ecluipmcnt at each interlocki~lg to provide the block signalling li~nction. WSA n i l 1 also install a renlotc field station in at each interlocking to pick up the indications for the CTC systcnl. 1-lle CTC workstations will display the layot~t of c;lcl~ interlocking but t11e indications ~vill only be active Sro~n tlre starting signals into the contr;rct ;Ire;l.

2.1 1 Power Supplies

Each station lias Sour optiolls of 220 \.olt clcctncal supply:

In the area of DAOP 111 between Soliggoril and Sindanglaut tlie capacity of the PLN supply is li~iiited and from the late afternoon llntil late ~n the night and for a pcr~od in tlre niornilig the voltage falls from 220 to 160 volts mlnlmum.
