With the conversion of the Apm and Bpm EC into domestic coaches, does
the SBB have enough international coaches left to replace the withdrawn
trainsets, or is most of the rolling stock for these "Ersatzzuege"
coming from Trenitalia (FS)?
Are the Cisalpino (UIC-Z) coaches still in use or have many of them
already been returned to normal SBB or FS liveries?
Are the replacement trains running to all the way to and from Milano or
only as far as either Brig or Domodossola, requiring a change to FS
