Long Island Rail Road operates trains consisting of 12 to 14 85' cars. That is a lot of platform to build. You got room for a 1020 foot long platform?
Compression happens by the number of cars that you operate. LION operates 6 car x 50' trains. NYCT operates 10 car x 60' trains for a 600' platform. LION cannot build 8' long platforms, 4 car trains just look too short and 8 car trains take up too much space. So, six car trains look just good enough.
4' platformms looks good on my layout. It is all a matter of how it looks to ewe.
