The evidence of Mr Cowling
15 Mr Cowling, who is also an engineer, gave evidence in the defendant's case. Although not employed by the defendant, it is clear he has spent a great deal of time examining issues related to the safety and performance of the railways and has given advice to and evidence on behalf of insurers of the defendant. His knowledge of the design and performance of trains on the city network is considerable.
16 He accepted that the defendant could have attempted to glue the gasket to the window frame and could have applied screws to each window. Indeed, after the accident, as an interim measure, the gaskets were glued. Mr Cowling did not believe that this alone would be an effective long term solution. Apparently the gasket will naturally deteriorate and with time the window could be forced out to its maximum opening unless otherwise mechanically restrained.
17 Mr Cowling examined many records and carried out extensive research into the details of railway accidents. He indicated that he had not found any record which suggested that people were squeezing through the windows prior to the accident. There had been incidents where people spraying graffiti when hanging out of carriage doors had been injured and killed but none which involved the use of windows.
18 Carriages of the silver double-decker type were first constructed and brought into service in the 1970s. By the late 1980's it was recognised that there was a need to upgrade them to provide locking doors and other modifications. Together with a program to fund the provision of a new type of train known as the Tangara, funds were provided to upgrade the silver double-deckers. It became known as the "CityDecker" upgrading program. Although it was intended that the program would commence in 1990 there were some problems. By May 1994, although the 775 carriages had been fitted with automatic doors, the rest of the program had not been implemented. This locking door program alone cost $4.5 million.
19 In May 1994 the CityDecker project was restarted at a cost of about $148,000 per car for the first 200 cars, making a budget for this batch of about $28.7 million.
20 The project involved upgrading with improved lighting, vandal resistant seating, repainted ceilings and walls, glass screen partitions between vestibules and saloons, slip resistant floors, tinted inward-opening hopper windows, high-visibility paint treatment to external ends of carriages, passenger "help-points" in vestibules and improved communications.
21 The implementation of the intended program was made difficult by problems with the Tangara. At about the time that the CityDecker program was to commence, an unprecedented increase in damage by vandals to the glazing of the Tangara carriages occurred, creating a major crisis in the availability of those carriages.
22 The design of the Tangara is such that although passenger safety was not at risk, the large external areas of glass offered vandals an easy target for missiles such as rocks and slingshots.
23 I understand that the glass replacement cost as a result of breakage was in the region of $400,000 per annum, which raised the initial need for consideration of a separate upgrading of the Tangara glazing system.
24 Apart from the direct glass replacement costs, this also meant that more of the non-Tangara rollingstock were required to make up for the shortfall in Tangara availability, in order to maintain the daily timetable requirements. The result was that the CityDecker upgrading could not proceed at the intended rate.
25 Up to June 1996 a total of 136 suburban cars and 38 intercity cars had been upgraded for a total cost of over $25 million.
26 Since then approximately a further 150 suburban cars have been upgraded each year under the CityDecker project for a total approximate cost of about $111 million.
27 If the defendant had believed it necessary, it may have been possible to modify the windows of the silver double-decker carriages before the accident as a separate task rather than replace the windows as part of the total upgrade of each carriage. However, because of the need to maintain fleet requirements for effective daytime operation, the work could only have been done in the evening when the carriage was undergoing its nightly cleaning.
28 Mr Cowling indicated that two people working together could have glued the rubber gasket at a rate of two carriages per night. The task could have been achieved as part of the normal maintenance operation but would have taken many months to complete.
29 If, however, in addition to the adhesive, two screws were inserted, this would have involved drilling and tapping, and although this may have been an effective solution to the problem, it would have taken four persons one night to complete the modifications to a carriage if the task was done as part of the normal maintenance procedures. At this rate the total program would have occupied some years.
30 As part of the general upgrade, the defendant embarked upon a major program to replace the windows on the double deck carriages. The new window was differently designed being an inward opening hopper with the consequence that there was no possibility of a person squeezing through it. The cost involved in modifying the window in this manner was obviously considerable, although because it was part of the general upgrade, it was not separately identified.
31 Mr Cowling observed many of the replaced windows. His evidence was that by the time they were being replaced many of the windows had reached the end of their useful life. In particular by 1996, windows were found without rubber gaskets or where the gasket had worn to the point where it no longer secured the window. If this was the case by 1996 it is obvious that many gaskets would have worn at an earlier point making it likely that many were in this state in 1994. As the windows were first constructed in the 1970s, this may explain why the plaintiff and his friends readily found windows which were no longer restrained by the rubber gasket.
Graffiti
32 From at least 1989 graffiti was a significant issue for the railways. Apart from the damage caused by the severe disfiguring of the inside and outside of carriages, by 1989 deaths had occurred when young people were hanging out of the doors of trains to spray graffiti. For this and other reasons there was a concerted program to provide automatic door closures. Even this modification did not stop a determined youth from blocking the door with a foot and leaning out of the opening.
33 Graffiti was common on the outside of single deck carriages, especially the older type known as "red rattlers". Graffiti was put on the carriages when they were parked overnight and was also sprayed on when the carriages were moving. Some of this graffiti was located around the windows although it was mostly around the doors. Mr Cowling had observed this graffiti but said that when associated with windows it was generally poorly formed, giving him the impression that paint was sprayed by someone putting his or her hand through the window rather than leaning out from it.
34 Evidence given by the defendant's employees indicated that prior to this event they had observed graffiti in various places including above the windows of trains. The strategy adopted to deal with graffiti was to inspect and clean the carriages every night. Apparently a major motivation for the graffiti vandal was the pleasure in observing his or her "tag" on the train. If it could be cleaned immediately the pleasure was lost and the desirability of applying graffiti diminished. This was the approach adopted by the authorities in New York. It was successful there and largely successful in Sydney.
35 As part of the nightly inspection the windows were also visually inspected for breakage. However it was not usual to carry out a close inspection of a window and no effort was made to determine whether the rubber gasket remained in place. To do this would have involved a greatly increased staffing requirement and a consequential significant cost.
36 Mr Phillip McColl, the Fleet Manager of the Flemington maintenance centre of the defendant, gave evidence that in 1994 he would, in the course of his duties, observe up to 160 to 180 carriages per day. He commonly observed graffiti on the inside of carriages and on the outside, within about one arm's length of the doors, windows and ends of trains. Although he said he could not recollect seeing graffiti on roofs, I do not accept this evidence. It is plain from answers he gave in cross-examination, that he had seen graffiti above the upper windows of double-decker carriages and the consequence is that the graffiti must have been on the roof. The only means by which this could be done would be from the upper level window. However, I accept that he did not appreciate that youths were squeezing through the windows and hanging out of the train to spray the roof.
37 Mr Michael Logue, the manager of fleet presentation at Central station at the time of the accident, also gave evidence. He said that amongst other places he had seen graffiti above the windows of double deck carriages. He confirmed that he had observed it on the roof of trains in a position similar to the plaintiff's "tag" by the time of the accident.
38 Although I am of the view that the defendant was aware that graffiti was being sprayed on to the roof of double-decker carriages before the accident, I am also satisfied that the defendant was not aware that young people were squeezing through windows and hanging their bodies out in order to spray the roof. If its officers had given the matter careful thought they would have realised this was occurring but because the opening, even without the gasket, was so small, the possibility did not occur to them.
39 Evidence was given about the design of railway carriages and the clearance for fixed structures beside the track. The minimum separation allowing for movement of the train through roll and wearing of mechanical parts is 525 mm. A youth hanging out of the train could readily extend beyond this safety margin and contact a fixed structure as happened in the present case.
