The bureau responsible for the high-speed rail programme has dismissed a suggestion that the new line should enter service ahead of its planned deployment schedule.

The rejection, reported by the Taipei Times, ends a proposal aimed at bringing forward the launch of high-speed rail operations. The bureau did not accept the case for early deployment, and the project remains tied to its existing timetable rather than an accelerated one.

No revised dates, revised ridership projections or changes to the rollout sequence accompanied the decision. The bureau's position leaves the deployment schedule as previously set out, with supporters of an earlier launch having failed to persuade the regulator of its feasibility at this stage.

The Taipei Times report gives no indication that the bureau plans to revisit the question. Any future debate over accelerating the high-speed rail deployment would need to address the operational and readiness concerns that underpinned the dismissal.
