Initially the telephone communication of RWF was met by a 400 Line MAX

Exchange for railway phones and BSNL connections were from Malleswaram

Exchange.

A 100 line EPABX of TATA make was installed in the year for providing BSNLconnectivity to the subscribers of RWF.

In the year 1996 the obsolete Strowger Exchange was replaced with anElectronic Exchange of LDBX Mark-II ITI make of 384 lines capacity and

further expanded to 624 lines.

After the commissioning of ITI Exchange BSNL facility was extended on theexisting intercom phones through software control in the exchange and theTATA EPABX was de-commissioned.

10 Channel UHF (Ultra High Frequency) System was installed for connecting

Rail Wheel Factory to the Indian Railways communication network throughBangalore Division. PRS (Passenger Reservation System) was introduced in

Yelahanka with data connectivity through UHF equipment and S&T

underground telecom cables.

In 2008 RWF changed over from Electronic Exchange to the latest state of the

art ISDN (Integrated Services Digital Network) Exchange of Coral Makeinstalled & commissioned by M/s HCL Communication Systems, Bangalore

with a capacity of 1024 ports with PRI (Primary Rate Interface) cards for BSNLincoming and outgoing, 1 PRI for Bangalore City access and 1 PRI for NDLS

connectivity and around 600 internal railway phones.

KTS (Key Telephone System) an EPABX Exchange providing intercom facilityto officers of RWF with a capacity of 96 ports was commissioned in the year2002 and in the year 2007 upgraded with the latest technology exchange of

Nitsuko make installed & commissioned by M/s Enkay Communications,Bangalore.

S&T department in keeping with the advances of Information Technologyextended internet facility to railway subscribers in East & West Colonies on

underground telecom cables using the broadband principle of operation,

connecting 84 subscribers in East Colony and 34 subscribers in West Colonyand a few connections in the Factory Area.

Stores department floats high vale tenders using the advanced technology by

E-tendering in RWF website for speedy processing of tender cases. FOIS(Freight Operating Information System) extended from Railnet Optic Fiber

Cable was introduced for extending this facility.

Conference Systems are provided in three locations in administration buildingand in the factory area for weekly meetings and during VIP visits to RWF.

S&T department is also maintaining Walkie Talkie system for cranecommunication in Wheel Shop.

S&T also provides Public Address System for official functions in Factorypremises, Stadium & Institutes in East & West Colonies.

ELECTRONIC LABORATORY

Since almost all the machineries are imported and having highly sophisticatedcontrolling system. Wheels and Axles are best on very high proven

technology which revolves around sophisticated electronics system and

software automation. With the involvement of this type of technologythe need of Electronics Laboratory has arised and initial setup with

starting infrastructure was carried out in the year of 1984. The mainthrust at that time of prevailing circumstances was of servicing of Electronic

systems / Sub-systems used in plant. Slowly with the expertise gainedand addition of further requirement of day to day needs the

diversification of Laboratory has taken place and it has ventured forthe other activities such as developmental works, Indigenisation

Calibration etc.

Apart from this the expertise which was limited to the RWF, with themanagement decision to extend demanding other Rlys / PUs. This hasfurther added feather to its cap by providing services to other Rlys /PUs. In which it has shown very appreciable quality of job & in lieu of

this appreciable amount of revenue also being earned.

As being ISO-certified , In this line Electronics Laboratory has setup its newsection called as standard cell (Calibration Laboratory) where almost all the

electronics Monitoring & Measuring Equipments used for quality checks arebeing calibrated, which are directly traceable to National /International

standards.

Laser Beam Detection:

In a rotary hearth furnace, the charge and discharge positions are fixed and

objects which are charged shall be discharged after it passes through all the

zones. It is very essential to see that the hearth does not index any further ifa wheel or billet (or any other charged object) is present on the hearth at

discharge station for two reasons- (1) Possible damage to the refractory wallbetween charge and discharge door (2) Possibility of Wheel/Billet going roundall the zones again if not discharged thereby changing the metallurgical

properties of the material.

Prevention of such an occurrence is more easily thought than done, due tohigh temperatures prevalent in the furnace. This problem is being solved by

directing the laser beam on the object with a sensor. The sensor shall senseno signal when the beam is interrupted by an object. The output of the sensor

is then brought into hearth index control loop.
