Transit connections
Norwalk Transit operates a connector shuttle bus service Route 4 which covers the 2.8 mi gap between the Norwalk/Santa Fe Springs Transportation Center and the Metro C Line station in Norwalk. All Norwalk Transit and LA Metro connections, including Route 4, are free with a Metrolink ticket.

Future plans
There have been persistent proposals, especially due to the original plans for the Century Freeway to connect to the 5, for a 2.8 mi eastward extension of the Los Angeles Metro Rail’s C Line from its current eastern terminus at Norwalk station to reach Norwalk/Santa Fe Springs station. This project carries a proposed cost of $321 million for an aerial bridge, and a $360 million cost for an underground tunnel. Since an initial Environmental Impact Review (EIR) in 1993, there has been no solid progress for this proposal. The Los Angeles County Metropolitan Transportation Authority (Metro) 2009 Long Range Transportation Plan (LRTP) lists funding priorities to build through year 2040 – the C Line east extension is not a funded project in the Metro's 2009 LRTP (or through either Measure R or Measure M) and is instead in the Tier 1 Strategic Unfunded Plan.
