As newspapers told, BLS will order 6 more NINA (Niederflur-Nahverkehrszüge = low floor short distance trains) to be added to the existing 8 ABe 4/8 525 001-008. It was said that thougts were made to include toilets as the working range of these trains was widened (against first plannings) with their use on "S-Bahn Bern" (they now usually run S5 Bern - Neuchâtel, S51Bern - Bümpliz Nord/Rosshäusern, S55 Bern - Murten and on weekends and in the evening S2 Schwarzenburg - Bern - Langnau). The 6 trainsets would replace the remaining two-car ABDe 4/8 751-54 and the Be 4/4 761-62.
BLS tries to place its order together with MO (Martigny - Orsières), which wants to buy 2 shortened trains (Be 4/6), and perhaps other railway companies. Nothing was said whether fianancement for the trainsets was secured.
