CHAPTER 11 MONITORING 1101 GENERAL - Track machines, being capital-intensive assets need track possession for working and shall be monitored on day-to-day basis at the level of division and headquarters. Both aspects of monitoring i.e. data collection & entry and generation of alerts/reports have to be meticulously done to reduce the response time and ensure optimum utilization of track machines. In addition, a system of periodical meetings at different levels is required for bringing to fore the issues affecting the smooth functioning of track machines and its organization and to generate solutions to the issues. These interactions will also serve to have finger on the pulse of the organization. It is desirable to design TMS module keeping in mind above aspects so that relevant reports reach the concerning officials in the hierarchy at pre-decided times periodically. (1) Data Collection & Entry - This shall consist of creation of data for the following (a) Machine details. (b) Section wise availability of corridor blocks for each day of the week. (c) Manpower, their deployment and various competency certificates. (d) Target and deployment programme.

The parameters shall be monitored broadly for two areas: - Working of machines affecting productivity and utilization, - Maintenance of machines affecting health. (1) Parameters for monitoring Productivity and Utilization of Machines (a) Productivity vis-à-vis Target - In the beginning of the year, railway wise targets for various types of machines are issued by Railway Board. These yearly/monthly targets should be broken into weekly targets and productivity monitored vis-a-vis assigned targets. The shortfall in productivity of machines should be made good by addressing issues such as health of machine, adequate traffic blocks etc. Efforts shall be made to achieve these targets and to ensure optimum productivity of track machines. (b) Adherence to Deployment Programme - The deployment programme issued for each machine in the beginning of the year shall be followed. It should be the endeavor of all concerned that no deviation in the issued programme is allowed. The performance shall be periodically reviewed to achieve the pre-decided deployment of machines in various sub- sections of division so as to complete the targeted work without any shortfall. It shall be the responsibility of track machine organization to make machine available to work in good fettle as per the requirement and deployment planning. Loss of time on account of schedule of the machine, major repairs, shifting etc. shall be minimized. The schedules of the machine i.e. 50 hrs, 100 hrs, 200 hrs, 500 hrs, 1000 hrs and also IOH, POH shall be meticulously planned and advance notice given to division for optimization of resources. The availability of each machine shall be worked out in terms of number of days machine is made available for work against total number of deployed days in each division. (c) Utilization of Machine – SBH, DBH and ABH - Railway Board has stipulated minimum block hours for each type of machine. All out efforts shall be made to operate traffic blocks equivalent to stipulated blocks hours thus making the Utilization ratio (granted blocks/stipulated blocks) as 1.0. Immediate steps for improving the traffic blocks for machines having utilization ratio less than 0.8 should be taken at appropriate level. (d) Performance of Machine in terms of rated output against achieved output - Rated output of machines per effective hour is stipulated for each type of machine. Ratio of actual output to rated output is a good 301  indicator of performance of machine. All out efforts shall be made to achieve performance ratio (actual output/rated output) as 1.0. Steps shall be taken to analyse and take corrective action for the machines having performance ratio less than 0.8. (2) Parameters for Monitoring Health of Machine (a) Monitoring of Prescribed Schedules of Machine - Prescribed schedules of machines as stipulated in relevant chapter of this manual, to ensure proper health of machines, shall be strictly adhered to and adequate time given for these maintenance works. Overlapping schedules shall be clubbed to reduce the down time of machine without compromising on quality of schedules. (b) Replacement Planning of Major Components/Assemblies - Major components/assemblies of machine shall be replaced in a planned manner and monitored at level of ZMD. These major components shall include: (i) Engine. (ii) Tamping unit. (iii) ZF and other gear boxes. (iv) Axles and wheels. (v) Pumps and motors. (vi) Other critical components as decided. All these important assemblies shall be serially numbered and performance of these components monitored in a centralized database for meaningful analysis and control. (c) Monitoring of consumption of oils and consumables - Consumption of consumables and various type of oils i.e. diesel oil, lube oil, hydraulic oil and gear oil are very essential to be kept under control. The daily/monthly reports shall form the basis and apart from cost aspect excess consumption will constitute a symptom, of ill health of a machine, indicating a need for corrective action. (d) Monitoring of consumption of Spares - While the consumption of mandatory spares requiring replacement at specified intervals will have to be on a set pattern, any excess drawl shall be critically reviewed. Similarly, case of spares consumed on repetitive basis, the root cause for such excess consumption should be analysed and corrective action to change the sub-assembly or going in for better quality of spares will have to be decided. The monthly reports will bring out the consumption forming the basis for this item. Issue of stores/spares at base depot shall be only with SSE/TM/ZD’s approval in the case of Imported spares and also when the stock is at a low level. 302  (e) Failure Analysis - Each failure of the machine or any of its components either during block or detected during maintenance shall be recorded and documented in the failure register. The failure analysis should be done machine type wise in following categories (i) Mechanical failure. (ii) Electrical failure. (iii) Hydraulic failure. (iv) Pneumatic failure. (v) Miscellaneous failure. Failure reports in the prescribed proforma shall begiven by SSE/TM/Line to SSE/TM/SDI and details along with remedial measures discussed during the monthly meeting held at the level of SSE/TM/SDI and Dy.CE/TM/Line. Failure reports of major nature and of those causing bursting of block shall be sent to HQ office also. Repeated failures and failure suspected on account of design shall be reported to RDSO for further study and analysis. Similarly, failures related to POH shall be reported to respective POH workshops. (f) Monitoring of Competencies of Staff and their validity - Track machine have to work in block section and accordingly staff have to in possession of various certificates such as PME, block competency, route learning, machine competency etc. This is to ensure that staff is fit to work in block section with track machine. A monitoring mechanism shall be put in place to ensure that all staff possess necessary fitness and certificates. Staff due for certification/examination shall be directed timely to the concerned authority for examination/training/certification. (g) Recording of machine parameters while working - Record of important machine parameters shall be kept by machine in charge while working. This may include various parameters such as squeezing pressure, squeezing time, tamping depth, vibration pressure in tamping machine, depth of cutting and lifting in BCM and SBCM. Monitoring of these parameters shall also ensure quality of the work done by the machine during block. Aim should be to develop such recording mechanism that records these parameters automatically while working. 1107 Reports and Documentation for Track Machines - The following reports/documents shall be used in monitoring of performance and other items in respect to working of machines: (1) Daily performance report – A daily performance report compiled by the track machine control based on the information/fed on-line or collected from all divisional engineering controllers/field staff. This will be a computer printout containing details of blocks demanded and actually made available, proportionate output achievable and actually achieved cumulative figures 303  for the month/year. Brief remarks for less output shall also be included for the information of CE/TM, CTE and PCE.
