Hi

As far as i know, the change of traction was made in Padborg, right at the border a few kilometers north to Flensburg, so they would rarely, if ever, come to Flensburg.
MX was redrawn from duty by DSB in Westdenmark i early 1991 and the last MY's was decommissioned from DSB around 2001.
Both are stil seen today i Padborg as the are operated by railcompanies like CFL and Contec

Yours
