My own guess—and it has to be a guess at this point—is that we're probably looking at a permanent increase in productivity growth on a sustained basis of about a percentage point to one and a half percentage points going forward. That means exactly what you've described: that the inflation-safe rate of growth in the economy or the inflation-safe level of unemployment, or the employment rate, is different from what it used to be, but there are still speed limits.

(Return tabled) Question No. 130 Mr. Francis Scarpaleggia: With regard to rail safety in Canada: (a) for the period of 2006-2012, which railways were permitted to operate with a single operator; (b) for the period of 2006-2012, which railways had permission to leave trains unattended for limited periods of time on main lines with or without an idling locomotive(s); (c) for the period of 2006-2012, which railways had permission to leave trains unattended for limited periods of time on side lines with or without an idling locomotive(s); (d) with regard to the railways in (b) and (c), under ...[+++] what specific conditions could the trains be left unattended; (e) what legislative or regulatory framework governs local emergency preparedness plans in the event of a rail accident; (f) with respect to the plans in (e), (i) who is responsible for creating and executing such plans, (ii) by whom are they audited, (iii) how often are they audited, (iv) against what criteria are they audited; (g) by whom and how often are municipalities through which freight trains pass provided with regular reports on (i) the state of local emergency preparedness in the event of a rail accident, (ii) the state and maintenance record of the railway lines within their borders, (iii) the materials, hazardous or not, that are transported through their jurisdiction; (h) if reports referred to in (g) are not provided, why not; (i) how many of the DOT-111 railway tank cars and the DOD-112 tank cars are in use in Canada, for each year since 2006; (j) for each year since 2006, how many rolling stock and track safety inspectors were employed at Transport Canada, broken down by (i) province of work, (ii) oversight responsibility; (k) for each year since 2006, how many rolling stock and track safety inspectors employed by Transport Canada were responsible for inspections in (i) the Greater Montreal Area, (ii) the municipality of Pointe-Claire (iii) the municipality of Beaconsfield, (iv) the municipality ...

The characteristics of the buffers and draw gear shall be designed in order to enable the safe transit of curves in the track with a radius of 150 m. Two units with bogies coupled on straight track with touching buffers shall generate compressive forces not higher than 250 kN on a 150 m radius curve. There is no requirement specified for two axle units.

A maximum passenger train speed in excess of the current maximum of 100 miles per hour on existing heavy freight corridors is fraught with difficulties: in maintaining the track to the close tolerances required for passenger operations under those speeds, due to the heavy loads imposed by freight trains; in balancing the super-elevation of the curves required for the mix of both fast and slow trains; and in protecting against roa ...[+++]d and rail conflicts at crossings at grade and against the possibility of trespass.
