My plastic freight car challenge

[modelsof1900]

At last my both boxcars are ready! (Unfortunately, I was for one week in a clinic, so that my whole work had to be stopped.)



Can you recognize differences by leaders and iron on the first sight? - Click on picture for a bigger view.



I removed all ladder steps at the darker T&NO boxcar in background and I replaced them by new steps made from wire - model was pictured before I have given it a color correction. I think that I have had a good quantity to do without an extremy great satisfaction. Or how do you see the result?
Because I did it not for placing this model in a showcase it was too many work and if these both cars will run in a train - I'm not sure if everyone will the differences. And so I will not rebuild the M&KT car also, I think.

I'm very interested very much in your opinion.
