queries regarding modelling a train in matlab

hey guys

i am new to matlab, i have few queries in it . is it possible to model and perform speed test on entire train (loco/maglev) which is on tracks in simulink ?.

And also we have to model individual components(engine/brake.etc) and assemble them together or there already exists file where it is sufficient to change values for components???

edit: read the question properly before answering. im not asking do this to me.

Is it possible? Of course. Start writing. Do you have an actual question about MATLAB, instead of just a doit4me? This is YOUR student project of course, not that of someone else. So it should be your effort made.

read the text properly before u answer, i havent mentioned anywhere saying " do it for me". all i asked is is there any inbuild file (like engine,transmission) in matlab so i can incorporate it and change values instead of building new one
