A railroad car part that is a partition or light cover, wherein the part is molded or formed from a thermoplastic polymer composition comprising: a total of 0.2 to 6.5 weight percent, based on the total weight of the polymer in the thermoplastic polymer composition as a siloxane-containing copolymer. Siloxane-containing copolymer, bromine-containing polymer in an amount to provide siloxane units, bromine-containing polymer in an amount that provides 9 to 13% by weight, based on the total weight of the polymer in the thermoplastic polymer composition, optionally as a third polymer, An optional third polymer wherein the sum of the weight percentages of the siloxane-containing copolymer, the bromine-containing polymer, and the optional third polymer is 100% by weight; And 0.05 to 10 weight percent light diffusion additive based on the total weight of the polymer in the thermoplastic polymer composition. |
