TITLE PAGE NO. 1 REQUIREMENTS SCOPE OF WORK REFERENCES TTC-SUPPLIED SERVICES TTC-SUPPLIED INFORMATION.9 6 TERM OF THE CONTRACT 9 Section 1 REQUIREMENTS The Toronto Transit Commission (TTC) requires a Company to perform a track geometric survey of its entire subway system and conduct rail profile scanning using mobile scanning technology. This mobile scanning technology is to be mounted onto a TTC rail vehicle. The TTC s subway system is comprised of double concrete box structure, bored tunnel, and at grade track sections, including 61 stations and 13 bridges. Nominal dimensions for the box structure is 5m wide x 4m above top of rail, and for the tunnels, the diameter is 5m, both as depicted on drawings attached herewith. Work conducted on mainline is governed by a strict set of operational rules and with traffic directed by the Transit Control Centre. Revenue hours generally run from 6:00 a.m. to 2:00 a.m., daily; except for the extended Sunday morning shift, starting from 8:00 am. TTC track gauge is non-standard, ranging from /8 to /8. There is a 600V DC power rail centred approximately 22 from the gauge face, with top of rail 4 higher than the adjacent running rail. Typically, the power rail is located to the left of track centreline, relative to the direction of travel, but can change from side to side when necessary. Horizontal restraining rail is used on curves having radii less than 2600 ft. with flange way of 1 7/8 to 2 1/8 (see applicable drawings for undercar clearance dimensions). Running rail is normally #100RA and #115RE. Special track work includes cross overs with different rail profiles and guarded crossings ( frogs ), thermal expansion joints, also guarded. The subway is a double track system, accommodating single direction travel only. Hi-rail type vehicles are not utilized. The survey should not take place in freezing temperatures to allow for soft spots detection and measurements, subject to the TTC s revenue operations schedule requirements. Section 2 SCOPE OF WORK 1. The Survey must be done twice, in both directions, and along the entire length of each of the Yonge / University / Spadina, Sheppard and Bloor/Danforth subway lines for a total distance of 240 km (single track length). Addendum No. 1

Measuring at service speeds (up to 80 km/h) during the revenue hours with contact power (600VDC) live. 3. During the measurement process, momentary stoppages at TTC stations to re-set measuring equipment may be acceptable subject to TTC operational requirements. However, if the equipment is mounted on a revenue vehicle, this cannot interfere with the operation of the TTC s regular revenue service. 4. The survey instrumentation must not, in any working or non-working position, infringe on the dynamic envelope of the TTC s Subway System. 3. The survey must measure following geometric conditions: 1. Track Gage 2. Superelevation or Cross level 3. Curvature (degrees or radius) 4. Lateral Alignment, 62-ft MCO (or metric equivalent) 5. Lateral Alignment, 31-ft MCO (or metric equivalent) 6. Lateral Alignment Space Curves, of user definable cut off wavelength. Any degradation of accuracy with lower speed to be quantified by the Company in the submission. 7. Vertical Alignment (Surface), 62-ft MCO (or metric equivalent) 8. Vertical Alignment (Surface), 31-ft MCO (or metric equivalent) 9. Vertical Alignment Space Curves, of user definable cutoff wavelength. Any degradation of accuracy with lower speed to be quantified by the Company in the submission. 10. Variation in Cross level over 62 and 31 feet 11. Lateral Twist 12. Warp 4. If the measuring equipment allows, the following optional requirements should be performed as part of the survey: 1. Flangeway (distance between the inside of the low rail (gage face) and the adjacent horizontal restraining rail (field side) at points right angles to each other and is measured 5/8 inches below the top of the running rail) 2. Measurement of above geometric parameters throughout special track work (switches and turnouts) 5. In addition to the above geometry parameters, the measuring system is required to provide: 5.1 Rail cross section profiles at the frequency of max every 1 and min 2 on each rail; 1. Identification of the rail size and correct reference rail applied to obtain the profile; 2. Vertical and lateral acceleration of the un-sprung mass. Addendum No. 1

Provide customs clearances and work permits, as applicable, and cover all associated expense to enable measuring and scanning services to be accomplished. 5.8 Data Processing and Report A summary spreadsheet shall be tailored to suit the data in question and should address, but not be limited to, the following: 1. Track Geometry: The location of data captured should be indicated relevant to the main line chainage, Station (if applicable), track direction, and track alignment (including curve data where necessary). All records should indicate a unique chainage (position relative to the relevant track markers), top of rail elevations and include other necessary location parameters; 2. Rail profile: Should be shown with the unique chainage. Profile of rail head should be scanned from the lower radius at intersection of field vertical surface and head underside to the intersection of gauge vertical surface to the head underside on gauge side, at minimum. 1. The horizontal rail wear should be shown at gauge side at 5/8 below the top of the measurement 2. The vertical rail wear will be shown as the vertical distance from the top of the new rail at intersection with the Rail centerline to the top of the rail measurement at intersection with the rail center line. 3. Size and cant of the rail should be recognized by measuring system and included for each measurement. 4. Alignment of the template and the measurement should be achieved by aligning non contacting feature(s) of the rail. Ideally reference point can be field side of the rail head lower radius, but other feature may be acceptable upon approval by the TTC. Rail profiles which cannot be aligned due to foreign material on the rail head (grease, dirt) must be detected by the software and flagged for manual alignment with possibility of elimination from the spreadsheet. 5. Measurements of the rail wear on the restraining rail and Special Track Work such as switches should be possible to exclude from other measurements but should still be able to measure the rail wear by individual analysis of the scan profile. 3. Acceleration of the un-sprung mass: Should be shown with the unique chainage. The format of this characteristic is best if shown in a graphic form, similar to strip charts and separately for vertical and lateral acceleration. However, the most convenient method of acceleration display can be agreed upon based on the industry acceptable standards. The accelerometer should have a Addendum No. 1
