& WAG9 classes of locomotives and its variants. It is fitted inside the machine room of Locomotive to detect smouldering fires as well as flaming fires that produce smoke. Fire Detection Unit gives an alarm warning signal to Cab-Pilot along with the LED indication.Fire Detection Unit contains two smoke detectors, suction unit with air-flow monitoring, visual indication of Operation, fault/malfunction, Alarm, connection for pipe with 25mm outside diameter, potential free relays. The unit works at nominal voltage of 24V DC.

B: PRESSURE SENSOR:
The Pressure sensor is made of piezo-resistive pressure sensor packaged in surface mount configuration and attached to a ceramic substrate, capable of an operating temperature(fluid temperature) of -40°C to +125°C. The sensing element associated with the amplifier and current converter,housed in a printed circuit board, will be embedded in a stainless steel housing. Packaged pressure sensor will work as a two wire sensor providing 4-20mA output corresponding to 0..4 bar pressure.
The differential amplifier will be housed in an aluminium enclosure. The differential amplifier has two input channels and each of these input channel can accept a 4..20mA signal coming from the pressure sensor. The output of the amplifier is the difference of the two input pressures(differential) and is provided as 4..20mA signal. Both input and output signals are connected to the amplifier through 5 pin circular connectors of type KPSE06E14-5S and corresponding mating receptacle in the amplifier housing.

C MASTER CONTROLLER :
The Master Controller developed by us will be suitable for WAP5, WAP7 & WAG9 classes of locomotives and its variants. It works using a different principle as compared to the master controllers currently being used in these classes of locomotives. The master controller has essentially three functional components, viz. (i) Angle Transmitter, (ii) CAM operated switches to sense TE (or BE), ZERO position, 1/3 position, 2/3 position & (iii) Forward/Reverse selector switch, which also has CAM operated switches and mechanically interlocked with the throttle handle.
The heart of the master controller is the angle transmitter, which is expected to provide a current output (4-20mA) proportional to the angle position of the throttle handle. We have developed a angle encoder using Contact less rotary position sensor over 360°. It has huge advantage compared to the currently being used.

D LOCOMOTIVE DIAGNOSTIC SYSTEM :
Locomotive Diagnostic Tool (Model LDS-04) was developed for trouble shooting and online diagnosis of the 6000 HP modern three phase locomotive fleet of Indian Railways equipped with MICAS-S2 control system of Bombardier Transportation. The equipment is built around a Pentium class processor and has a communication gateway enabling direct connection to the locomotive control system through the Multifunctional Vehicle Bus (MVB). The diagnostic tool becomes a network node on the MVB and all the vehicle processors can be accessed. The entire suite of MicTools (proprietary traction control software tools of Bombardier Transportation) can be run on this equipment to carryout many functions like control software download, fault log upload cum offline analysis, visualization and temporary forcing of process variables in real-time etc. The equipment is very compact, chassis cooled with dual input supply option of 110V DC and 230V AC 50Hz. USB interface and dual boot feature (DOS & Windows) are its unique features.

E FUNCTIONALLY EQUIVALENT PCBs :
The present running 3-phase Electrical Locomotives using the design of MICAS S2 class of Electronic PCB’s are of late 1980’s vintage. Many components have already been declared obsolete by the OEM’s years ago. Due to this, the genuisness of many parts which are currently being purchased is not very certain. The failures are likely to increase in future and maintenance could be a serious problem.
To overcome such difficulties we have undertaken re-design of MICAS S2 electronic PCB’s retaining the same functionality and straight-away interchangeable. In this connection we have already developed 3 types of PCB’s namely: 1. AR B705 B01 Signal Routing Board 2. UF B660 A01 MVB Bus Coupler Board 3. UF B701 A01 Bus Coupler Board.
