What is a double step back?

Normally during rush hour when a train pulls into an end terminal, the crew from the previous train to come in "step back" to operate that train so it gets out of the terminal quicker while the other crew has a bathroom break. Even with the extra time the trains weren't leaving as soon as they could so management decided to try "double step backs" where the crews would wait for one more train to depart before taking over one themselves.

The Speed Control System
After the Russell Hill crash, the jury from the Coroner’s Inquest made many recommendations related to the TTC’s signal system and train operation. The change of timing signals to show a flashing red (described above) was one outcome.
On November 28, 2001, the Commission authorized the installation of a Speed Control System (SCS) on the existing subway system (YUS and BD) and on the Sheppard Subway which was still under construction. The contract was awarded to Alcatel for $29.5-million.
The new SCS will provide continuous on board enforcement of train operating speed limits, as recommended by the Coroner’s Inquest, and will provide enforcement of all signals. The SCS will issue a violation warning to the train Operator when a speed limit is exceeded. If this warning is not complied with by slowing the train, an emergency brake will occur. Emergency brakes will also be applied if a red signal is violated, thus enhancing system safety. The SCS will provide other important safety benefits in the subway, such as enforcement of a stop at track ends and enforcement of a speed limit when a train is travelling in the reverse direction.
The SCS will replace the current Grade Timing method of speed enforcement, which uses timer relays as well as lunar white and flashing red aspects to enforce speed limits. [p. 1]
SCS uses transponders mounted between the rails to communicate with control equipment on the trains. This system enforces speed restrictions, but track occupancy and routing control remain the responsibility of the primary signal system. SCS provides a way for the signal system to communicate directly with the trains without depending on the operator, but it does not control train operation except for enforcement of speeds and emergency stops.
Although the 2001 report claimed that SCS would replace the timing signals with their lunar whites and flashing reds, these actually remain in use in 2015. Decommissioning all of the existing timing signals and their controls would be a complex job better left to a project that completely replaced the signal system.

The 501 has been a disaster for the past 2 weeks with various incidents plaguing it, this is just another. You name it, its probably happened: vehicle accidents, passenger emergencies, various mechanical failures, trolley poles getting caught, police investigations. During the peak periods and right after peak periods, people are better off just walking because this line is just an embarrassment.

I was on the 501 (bus+streetcar) from Park Lawn to almost Neville Park this afternoon. The ride went perfectly fine. It wasn't stuck in traffic and had plenty of standing space.

The mechanical failures are a problem but sometimes stuff happens and the TTC can't prevent everything. Let's ease off the drama pedal.

Though the TTC on-time stats speaks for itself - and that data is not even isolated to the rush. If stuff is happening so often to make people avoid using a transit route unless they absolutely have to we have to is a bit of an issue, to put it mildly.

501 reminds me of the old nursery rhyme.....when it is good, it is very very good, but when it is bad, it is horrid.
TTC ought to manage this route better, but sometimes the inconvenience is something you just gotta live with.

Could the TTC do better? Sure. But the City/Transportation Department/Traffic police do not create the conditions for TTC to succeed with surface transit downtown even if TTC did everything right (transit priority at intersections, providing money for proactive maintenance, limiting parking, enforcement of no-turn/no-park/no-stop)

None of which anyone will be willing to touch unless there is drama. Haven't Toronto tried the "keep calm and carry on" tact and gotten pwned? I think the experience have shown that playing nice gets you nothing in the current environment.

The lived experiences of downtowners is not politically important with the current administration.

TTC's Downsview Station becomes Sheppard West
April 20, 2017
Starting May 7, TTC's Downsview Station will be renamed Sheppard West Station in advance of the opening of the Line 1 extension to York Region later this year. Customers will begin to see "Sheppard West" on signs and maps over the course of the next few weeks as the transition takes place.
The name change is being made to accommodate the new Downsview Park Station, located inside Parc Downsview Park. Use of "West" on stations with street names is commonplace on the system, making this change consistent with current practice.
Among the items being changed or revised for the name change:
- 30 signs in and around Downsview Station
- 123 destination signs in other TTC stations
- 161 platform 'You Are Here' maps in stations
- 3,184 maps on subway trains
- 4,000 maps in transit shelters
- 250,000 Ride Guides
Changes also have to be made to passenger information systems and announcements in trains as well as the TTC's back-of-house and service planning systems, and the Transit Control Centre.
The name change will cost approximately $800,000, the majority of which ($600,000) is related to the reprogramming of Bombardier's proprietary announcement system on the Toronto Rocket subways. That reprogramming includes both this name change and the addition of the six new station announcements that will be needed when the full extension to Vaughan Metropolitan Centre opens.
The TTC thanks customers for their patience during this transition period.

Why don't they just do the two changes at once? Seems stupid to change all these signs and subway maps when they'll have to do it again in nine months.
