If you are going for scale, yes, it is too large. 

Now if you were doing G scale you'd be in the ballpark with that.

It would be too large for O. Now, if you want place the truck in the foreground to create some forced perspective with the trains in a middle background, that is one way you could use it. 

Like stated....scale?? Way to big!!! But if you are doing a layout that is more TOY theme I see 1/32 all the time.....along with 1/54 scale vehicles and giant figures........so do what makes you happy!

Not what he asked. He knows whose layout it is. He is looking for modeling opinions, not permission. "It's your layout" is never helpful.

Now, to address the question: holy cow, that's way too big. Think about it. It would look, to use a technical modeling term, stupid.

1:32 is #1 scale (as in the big MTH line), not #0 (the proper "O gauge" term - it's a zero, not an "O") scale. 

1/50 scale is best for "O" gauge.  1/48 is a bit too big.

1:48 is exactly the correct scale for vehicles on an O gauge layout. 1:43 is a common size for die cast model cars but it is too big by about 12%. 1:32 is 50% too big for O gauge. 1:50 is 4% too small for O gauge. Many O gauge/scale modelers accept 1:43 and 1:50 scale vehicles as accurate enough to use as scale models on their layouts.

I have 4 of these 1/32 cars. Love the details and bought them for $10.00 each.  I put one on the largest flat car I have. You can see it does just fit.  Good luck on building your car.

For those interested in gauge and scale for toy and model trains: I wrote an e-book with many pictures about this subject which can be downloaded for free from my website: http://sncf231e.nl/gauge-and-scale/
