An HO model of a LIRR P-53A class coach, built by ACF car foundry in 1902.

This would be the first series P-53A coaches built, with two more series of similar dimensions being built by PRR in 1906 & 1907. This 1902 run was numbered from 300-309. They were also ordered in addition to the P-53 coaches, which lacked Vestibule enclosures. 

Color should be white or cream letters with the body being LIRR Coach Brown (A sort of darkish Maroon in color). I have used Apple Barrel Red as a close approximate.. it is also a good approximate to PRR Tuscan Red. Roof can also be painted Black. Handrails for the roof will also need to be fashioned, and trucks are not yet supplied with this model. Decals will need to be sourced separately. For reference as to livery lining & lettering arrangement, please refer to this lovely builders photo brought by the Delaware Public Archives, which can be found by clicking here.
