Source-derived summary

Siu Sai Wan Extension (Chinese: 小西灣綫) was a proposed extension of the Island line to Siu Sai Wan on the eastern end of the Hong Kong Island. A plan was revealed in 2001 after many calls from the Eastern District Board (later District Council) since 1991. Although the population size in Siu Sai Wan is large enough to support a station, the plan was later shelved, despite continued calls from the Eastern District Council.

Proposals

In February 2013 review and update of the Railway Development Strategy 2000, Highway Departments proposed three schemes to extend the current railway network to Siu Sai Wan area, either by extending after the current Chai Wan terminus, branching off from Heng Fa Chuen station or constructing a new medium capacity railway system from Heng Fa Chuen.

Extension

An extension would have extended the Island line from the current south-eastern terminus Chai Wan station to Siu Sai Wan. The alignment of the existing Island line, however, made it difficult to extend the line from the terminus Chai Wan station. Such an extension would have required a U-shaped tunnel passing through Pottinger Peak. Certain nearby buildings would have needed to be demolished to make space for the extension.

Bifurcation

An alternative plan was to build a Y-shaped branch from Heng Fa Chuen station. A bifurcation would require reclamation of the Chai Wan Cargo Handling Basin.

Editorial summary

This brief starts where responsible research should: with the source description of “Siu Sai Wan Extension” as proposed railway line extension in Hong Kong. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—2001, 1991, 2013, 2000—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Extension, proposed and railway can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as proposed railway line extension in Hong Kong. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q6420650. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2001, 1991, 2013 and 2000.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
