About The length of this line if set in the 70's would be about 173 km (107 mi). Both fright and passanger services would be possible. The location of this route is Queensland, Australia. dont know how many stations there are or how many yards (at least 2). This route would include Mayne yard where locomotive and carriage sheds are located. Fright service as of current go via the Exhibition loop while commuter train go via the main corridor. I'm not sure how it worked back then if that was the case the addition of the the extra bit of track would only add an additional about 4km of route bringing to total route length up to 177 km (109 mi) (roma street 1983, doubt much had changed if anything since the 70's) (what is now Old Gympie station in 1987 there were some changes between the 70's which have been documented) Locomotives (all should of operated in some part of section but could be wrong) 1150 class (GE) Wheel arangemet: Co-Co Total produced: 13 1250 class (EE) Wheel arangemet: Co-Co Total produced: 17 1270 class (EE) Wheel arangemet: Co-Co Total produced: 30 1400 class (EMD) Wheel arangemet: A1A-A1A Total produced: 13 1450 class (EMD) Wheel arangemet: Co-Co Total produced: 10 1460 class (EMD) Wheel arangemet: Co-Co Total produced: 18 1502 class (EMD) Wheel arangemet: Co-Co Total produced: 29 1620 class (EE) Wheel arangemet: Co-Co Total produced: 34 1720 class (EMD) Wheel arangemet: Co-Co Total produced: 56 DH Class (Walkers) Wheel arangemet: B-B Total produced: 73 Passanger stock BU BUV SX 1800 class rail motor 2000 class rail motor
