This is the Abbscroft Town City Line, which runs from Hertford West to Stanley via Lakeview Way. This line has a total of 11 stations. It also is very fast. There is different signage, as the line used to be the South Lakeview Railway (Lakeview Way was originally South Lakeview). The South Lakeview Railway signage is blue while the Abbscroft Town City Line is pink. After the eleven stations, you will arrive in Stanley & Old Common depot and then Hertford West depot.
