Rainford lost its "Junction" suffix a fair while ago (around 1972/73 according to my old BR-LMR timetables). It's interesting that the settlement around Rainford station, which is separated by a short distance from Rainford village, is still known as "Rainford Junction" by locals and appears as such on Ordnance Survey maps.
Clifton (Junction) on the Manchester/Bolton line is another example. The station lost the Junction part of its name long ago, but the industrial area adjacent and to the north still appears on current OS maps as "Clifton Junction" (the rail station is correctly marked as just Clifton).
A third example of this is Lostock, west of Bolton. The old Lostock Junction station closed in the 1960s (& has been re-opened with platforms only on the Chorley line, so definitely no-longer a junction), but the residential area around there is still known as Lostock Junction to differentiate it from the part of Lostock along Chorley New Road.
The OP's question related to station names, but there are possibly small settlements up and down the country called "XXXX Junction" where there is no longer a junction, or a station nor even a railway.
