Question

Assessment 4.0: Management of Quality

Produce a report (min 300 words) detailing construction methodology and the process for the management of quality of installation and progress reporting for either of the following:

• Plain line track renewals
• S&C Installation

Include in the report an outline the management of quality of high output techniques for the following:

• Plain line track renewals
• Ballast cleaning
• S&C Modular Installation methods

Also include the management of quality of track renewals process for special circumstances including:

• Tunnels
• Viaducts
• Other local areas of specific constraint (if appropriate)

Answer 1

Plain Line Track Renewals

Plain lines are the stretching of the railway tracks without any junctions or cross over points on it. These lines need to be renewed after proper intervals. High output track renewals allows network rails to replace more and more tracks ensuring the safety of trains. The plain line method is applicable for simple stretches of plain line. The quality systems are being installed so that there are not many casualties and the output quality is better. The blast cleaning high output machines would require an underlying formation technique.

High quality output requires good management which is being shown in this method. The renewals are collaborative process from the planning stage to the last delivery stage. It is a 24 hour cycle process that needs to be managed and work is divide in bits and pieces such as getting the systems ready in operation, prepare the track by removing lineside equipment, starting up machines and bringing back old materials. Ballast cleaning is also a procedure needed to obtain good quality in line renewals, these machines specializes in cleaning the railway track ballast of impurities. These machines may be undercutter or blast cleaning machines.

Some different techniques are to be followed when renewal is needed to be done in tunnels or viaducts. Viaducts are long bridge like structure that are made in form of series of arches made for transportation of trains through valleys and forests.These are made since many years. The positive aspects in dealing with these are that they present good challenges in renewal of rail lines. Overhead line equipment has to be installed while dealing with viaducts which means the distance needs to be greater between the railway and any bridge above it. So the over head equipment fits beneath the viaducts.
