I was just looking at the press releases from the RhB from last May,
where they eplained their rolling stock replacement program. The
units we are looking at in this thread are essentially built for the
requirements of the Bernina line (where the 40 series motor cars are
apparently in urgent need for replacement). That means that the
replacement units were designed to haul the maximum allowed load on
the Bernina line. Comparing with today's patterns, they are replacing
a set of a 40 series and a 50 series motor car in MU. Looking at the
specifications, these units have more tractive force than the
Ge4/4III (which is easy to explain because of the 8 driven axles).
And also according to the specs they can maintain that maximum
tractive force up to approximately the speed on the Bernina line
grades. But, compared to what they replace, they offer more passenger
capacity, and -- even more important -- accessibility because of the
low-floor entrance (something which is required by law).
So, this makes these units definitely well suited for steep grades,
and that's where they are intended to be used besides the Bernina
line: Chur-Arosa where the current operation pattern is not really
the very best, and Landquart - Davos expresses, where they can
provide additional capacity.
So, as Markus said, there is no need for MUing them; remote
controlling, however, yes.
