| Hi.
I bought the 10261 roller coaster a while back, and built it this weekend, but
unfortunately it was a disappointment, as the trains will not run down by themself,
there are way too much friction. I have seen videos from reviews where it works
perfectly, so I wonder if anyone else have had the same problem as me?
It's not that I haven't built it properly or something like that,
and it is not even close to working, with either a train nor a single car. If
I manually push one car from the top with a lot of force I can get it to come
up the first up-hill after the initial drop, but there is no way I can make it
go around the bend to the next down-hill. And it is the same everywhere else
on the track, i.e. starting a train with the break-wheel will not get it past
the first bend to the elevator-track.
I have noticed in this set as well as in some other sets that I have bought recently
that the feel of the bricks are different, the plastic feels kind of rubbery
to the touch, and I have assumed that lego have changed the type of plastic they
use. Anyone else that have noticed this and/or know if they have changed their
plastic in the last 2 years or so?
My thought is that it is a new plastic, and that is has more friction (both for
the wheels to rotate, as well as towards the track), and the reviews I've
seen that is four years old had the old plastic. Otherwise I don't know what
it could be. It was a sad final to hours of building

Are you really sure?
Have you correctly put the wheels in the cars? If they are not pushed far enough,
the struts on the bottom of the car that ‘join’ the car to the rails will also
block the car.

For now, the only really ‘new’ plastic that LEGO has introduced is the MABS/transparent
ABS… for transparent parts. And I think that started even before 10261 was out.

Please, check the wheels
