As part of the GO expansion component of Metrolinxs Regional Transportation Plan, Metrolinx plans to modernize southern Ontarios GO Train system by adding stations, increasing system capacity, introducing 25-kV electrification, replacing its diesel locomotives with electrified locomotives, immunizing its existing fixed-block
signaling system to the 25-kV traction power supply system, and deploying Enhanced Train Control (ETC) on the GO corridor and its train fleet.

The answer came with the realisation that the moving-block system being proposed by the British supplier had an underlying fixed-block
Progressive Deduplication Is Content-Aware Arkeia's progressive deduplication is based on advanced algorithms that constitute a major advance beyond fixed-block and variable-block deduplication.
Source-side Deduplication Reduces Network Load Unlike fixed-block deduplication, the first generation and most common technology for deduplication, Arkeia's progressive deduplication accommodates data inserts into files, as well as file appending and modification.
All files previously encountered by Arkeia are deduplicated at fixed-block
The DVH models can be equipped with either fixed-block
tooling or a turret with VDI tooling.
There were three conditions with a fixed-block format, in which the distribution variance from which the source values were drawn remained fixed across stimulus trials.
In the fixed-block conditions, all display and distribution parameters were fixed within a block of 115 trials.
Among the fixed-block conditions, one included an observation period that preceded the signal detection task (e.g., the fixed-observe condition).
Subsequent analytic comparisons (t tests) with a Bonferroni adjustment for the error rate indicated that in all three fixed-block conditions, there was significantly better performance (p [less than] .008) than that found in the random-block condition; otherwise there were no significant differences among the conditions.
