but added that this proposal had not been implemented at the time of the accident.
87 Dr Wigglesworth also noted that on the SRA's own assessment, there were inadequate sighting distances in three of the four quadrants and that the overall assessment of the level crossing was that sighting distances and vision angles were not acceptable. Dr Wigglesworth continued that:
"… this internal Assessment Report gives a very clear warning that in three of the four quadrants (including the quadrant relevant to the collision in March 2001) the sight distances fell below the guidelines set out in the [Draft Standard]."
88 Dr Wigglesworth commented that at management level, the SRA was well aware of the problems with sighting distances and that the solution, if sighting distances could not be achieved, was to reduce train speed. Dr Wigglesworth's observation was well made, based as it was on the SRA's own internal documentation.
89 His Honour referred to Dr Wigglesworth's evidence as follows:
"[282] … where sighting distances cannot be achieved, one strategy adopted by [the SRA] involved the reduction of train speeds which he considered to be an 'entirely appropriate' treatment of the issue (p.22 of his report). He noted that suggestions recorded in a file document to slow trains on the relevant section of track to 93 kilometres per hour in the 'down' direction had not been implemented with the maximum permissible train speed being fixed at 125 kilometres per hour. However, whilst that appears to have been the case, as noted earlier, the train in question was driven, prior to braking, at 92 to 93 kilometres per hour …"
90 The appellant contended that his Honour, at [282], apparently failed to appreciate that Dr Wigglesworth's evidence that the maximum speed for the train was 93 km per hour was based on a sighting distance of 481 m, whereas on his Honour's own finding the sighting distance was approximately 400 m. However, for the reasons I explain below, this submission is based on the premise, which the respondents challenged, that the "sighting distance" of about 400 m was a sighting distance that could be related to the requirements of the Draft Standard. The SRA did not dispute the various calculations referred to above. However, it submitted that the appellant had failed to establish that the sighting requirements and speed limits did not comply with the Draft Standard.
91 This argument involved two propositions. The first was based upon what the SRA contended was the proper way of interpreting the Draft Standard. The second proposition was that his Honour's finding of a sighting distance of approximately 400 m could not form the basis of the finding for which the appellant contended, namely, that the maximum speed for the level crossing should have been 75-82 km per hour. The SRA argued that the underlying factors upon which the sighting distance of 400 m, was found by the trial judge, were different from the underlying factors upon which the Draft Standard was based. In short, the argument was that that the appellant was seeking to make an apple do the work of an orange.
92 The SRA submitted that the table and notes set out at [82] above are to be interpreted in the following way. A semi-trailer 17.5 m in length (see note 1) approaching the level crossing from a distance of 5 m and crossing the track and clearing it by another 5 m, travels a total distance of 28.9 m in a time of 12.6 seconds. For design purposes, a safety factor of 5 seconds was then built into the equation (see note 5), so as to calculate the minimum sighting distance. The calculation was also premised on a vehicle starting from a stationary position (that is, having stopped at the stop sign) and gaining a speed of about 10-12 km per hour by time it had cleared the crossing (see note 6: vehicle clears crossing at 3 m per second). The various speeds were calculated on the basis that vehicles were fully laden (see note 2).
93 Further and more importantly on the respondents' case, sighting distances were premised upon lines of sight taken at a specific location and measured from and to specific heights. Thus, the sighting distances in the Draft Standard, for vehicles other than a car were based on a survey measurement taken from a viewing point located 5 m from the nearest rail (which the designated viewing point) at a height of 1.8 m above the ground looking to a point representing the train at a height of 3 m above the rail track. In the case of the Xplorer, which was 4.1 m high, that meant that the sighting distance was determined by measuring the distance from the designated viewing point to where the top 1.1 m of the train could be observed. It appears that this railway line was also used by other types of trains (the suggestion was that it was used by freight trains) in which case, the height and, therefore, the relevant sight distance, would be different. However, it was not suggested that any other type of train would travel at a speed material to the maximum permissible speed.
94 The respondents contended that it could be deduced from these various calculations that for a train travelling at 93 km per hour (being the speed of the train here), the sighting distance was 454 m. (The sighting distance in 1994 was, or course, measured to be 481 m.) Again, as I understand the case of the appellant, it did not cavil with the arithmetic calculation. Rather, it submitted that there was a finding that the sighting distance was about 400 m and it was in respect of that figure that the maximum permissible speed ought to have been calculated. That argument leads to a consideration of the second of the propositions raised by the respondents and arises directly from the analysis which has just been undertaken.
95 The respondents submitted that the sighting distance of about 400 m, as found by his Honour, was not referable to the sighting requirements of the Draft Standard. The respondents submitted that whereas the sighting distance of 481 m was established by survey and in accordance with the methodology just described, the sighting distance of about 400 m was not. Rather, it was an approximate distance, taken from a different location and estimated from a different height, than that specified in the Draft Standard and was based upon essentially generalised measurements taken by Constable Wheelhouse and by an RIC officer, Mr Sheehan.
96 Constable Wheelhouse's evidence was that he walked 300 m south of the crossing and from that point kept looking backwards to the stop sign and that it was not until he had walked 400 m that he could no longer see the stop sign, which he estimated to be about 6.5-7 feet high. Constable Wheelhouse was 190-192 cm, or 6 ft, 35 in tall. He estimated that from where he stopped at the 400 m mark, the top of the stop sign was roughly level with the train driver's line of sight. The lack of accuracy in these measurements is obvious. In any event, the line of sight is measured from the perspective of a driver of a vehicle, not from the perspective of a train driver.
97 In 2001, Mr Sheehan was employed by RIC as a track supervisor. He had previously been employed by the SRA when it still had the responsibility for the infrastructure of the level crossing, as outlined earlier. He was responsible for the railway track between Gunnedah and Werris Creek. One of his tasks as track supervisor was to oversee the spraying of grass and noxious weeds. He said major spraying was carried out three times a year, but that the track was under a regular, 72-hour inspection cycle. There was also evidence that grass and weeds could grow to a height of 1.5 m. However, there was no evidence of grass or weeds of this, or near this height, on the day of the accident.
98 Mr Sheehan's duties also included preparing an annual Track Examination System report on the condition of all level crossings in his area. One of the specific requirements of such an inspection was to check for any obstructions to sighting distances caused by grass and scrub. Mr Sheehan carried out the annual examination on this crossing on 14 March 2001, in which he assessed the sighting distances in quadrant a 1 to be 416 m. He described the manner in which he did this assessment in the following terms:
"… the way that I always checked the sighting distance at Breeza for trains travelling on the down (that is, trains coming from the direction of Werris Creek) was to stand at the stop line on the up (north) and down (south) side of the level crossing and look for the kilometre peg in the up direction (that is, towards Werris Creek). The pegs are about 5 foot high and are located at the toe of the ballast about 2.5 metres from the nearest running rail … The nearest kilometre peg to the Breeza crossing on the down side … is about 416 metres to the east of the level crossing. If I could see the kilometre peg from the stop line on the down side of the level crossing I would write 'OK' or place a tick on the form, in the box under 'Grass and Scrub'."
99 The respondents submitted that Mr Sheehan's evidence could not form the basis of a finding as to the "sighting distance" either, as that term was used in the Draft Standard. Mr Sheehan's measurement was only taken to a specified distance without any evidence as to how far beyond the kilometre peg Mr Sheehan could see. Nor was the measurement taken from the height specified in the Draft Standard.
100 The respondents also pointed out that the appellant had failed to tender any survey evidence evaluating the visibility of the Xplorer train (or other trains) in accordance with the Draft Standard, despite relying extensively on survey evidence for other parts of its case. This submission was directed, in particular, to the inadequacy of the Bath Stewart survey evidence tendered by the appellant. The respondents made two particular criticisms of this survey evidence, in addition to the generalised one just mentioned. First, Bath Stewart did not evaluate the sighting distance in accordance with the Draft Standard. On the survey, the top 2.4 m of the Xplorer train would have been visible at a distance of 425 m from a viewing point positioned 1.8 m above the ground and 8 m from the nearest rail (instead of 5 m as required by the Draft Standard). Secondly, the survey failed to take account of the fact that Mr Stackman's actual line of sight was higher than the 1.8 m specified in the Draft Standard.
101 The respondents submitted that the trial judge concluded correctly that the Bath Stewart report did not provide a reliable guide for evaluating the issue of train visibility. In this regard, his Honour said:
"[301] … It was not based upon accurate data relevant to the truck driver's eye height in determining the observability of the train and it was based upon scenarios calculated by reference to distances from the stop line not the stop sign ." (Emphasis original)
102 In my opinion, the respondents' submission that the appellant had not made out this aspect of its appeal should be accepted. His Honour's finding of a sighting distance of approximately 400 m was a non-technical measurement which could not be used by the appellant to establish what was fundamental to its case, namely, that the speed limit at this crossing should have been, at the very least, no more than 82 km per hour. There was no evidence of the technical sighting distance relevant to the assessment of a safe train speed, other than the November 1994 assessment of 481 m. There was no evidence that the top 1.1 m of an Xplorer train was not observable at a distance of 454 m, being the required sighting distance for a train travelling at 93 km per hour to give a semi-trailer a safe clearance time of 17.6 seconds, in accordance with the Draft Standard. As I have said, the train was travelling at about 93 km per hour. Nor was there evidence concerning the non-observability of other trains at a distance of 454 m.
103 There was no evidence that this sighting distance had been reduced or obscured by overgrown vegetation. The evidence accepted by his Honour was to the contrary. The configuration of the track had not changed. Accordingly, once the appellant's case based on overgrown vegetation and trees was rejected, the only evidence of the technical sighting distance at the relevant quadrant of the crossing was 481 m. It may be that there was an oversight in his Honour's reasoning in not explaining the difference in technical sighting distance measured so as to properly assess safe speeds for trains at level crossings. However, at trial, the respondents advanced the same argument and, in my opinion, it defeats this aspect of the appellant's case based on contributory negligence.
104 It will be apparent from my reasons in finding that the SRA was not contributorily negligent, that it did not fail to exercise reasonable care. Accordingly, to the extent that the appeal also related to the SRA's primary liability, that aspect of the appeal must likewise fail.
