Many of the major US railroads all have business trains, and some of them (for example: UP and NS) have excursion passenger consists and locomotives. It could be cool to see DTG (or a 3rd Party Developer) add OCS, Excursion, and Business Train locomotives and rolling stock to TSW4. Here are my suggestions. -BNSF OCS Train DLC for Cajon Pass: -Possible Locomotives: -ET44C4 -ES44DC -Rolling Stock: -All passenger cars in BNSF fleet -Interior view of passenger car (preferably a dome or observation car) -UP Excursion Train DLC for Sherman Hill (also could be operated on Cajon Pass, Antelope Valley, etc.): -Possible Locomotives: -UP Big Boy #4014 -UP FEF-3 #844 -UP E9m A-B-A -UP SD70M #4015 (for use with steam locos; also SD70Ms could be run on freight services) -UP Challenger #3985 (no longer on roster, but should be added in the pack or as a DLC) -UP DDA40X #6936 (also no longer on roster, but should be added) -Rolling Stock: -All passenger cars; interior view included -Include auxiliary water tenders -NS OCS Train DLC for Horseshoe Curve: -Possible Locomotives: -NS rebuilt F9 A-B-B-A Set (no longer on roster; units still in service on shortlines) -NS SD60Es (regeared for passenger service) -N&W J-Class 4-8-4 #611 -Rolling Stock: -N&W aux. water tender for #611 -All passenger cars; interior view included -CSX OCS Train DLC for Sand Patch Grade: -Possible Locomotives: -CSX F40PH (already in game with Peninsula Corridor; needs modifications to match CSX units; include B&O-liveried unit) -Rolling Stock: -All passenger cars; interior view included
