Ok this is going to be a long winded post but here its goes. I felt the need to sit down and review my operation and approach it from a prototypical standpoint and figure out just what it would take to operate my system. I am hoping that this will help others determine what their individual empires will require as far as realistic roster sizes. I am going to break my entire system down for you yard by yard and every job based out of each yard along with their operational duties and needs. My operation covers 285.25 miles (including trackage rights) over 9 lines and operates five yards. Here is a link to my map so you have an idea of what the railroad covers.
www.google.com/maps/d/edit?mid=zzT28ywqyOHU.k6tnXnwGVGz0 So here we go.
Hagerstown Yard:
Hagerstown directly serves the Chambersburg Sec, Roxbury Sec and the Potomac Connection. Along with these local lines Hagerstown serves as the westernmost interchange location making connections with CSX, NS and the Winchester & Western. The jobs based out of Hagerstown are:
HY-1 Hargerstown Yard job
This job is responsible for shifting out inbound/outbound interchange traffic in the yard and building trains for the local crews when time allows. The plan is to run this job with a mother slug set.
HG630 Hagerstown local
This job will be responsible for serving the industries along the three lines served by Hagerstown Yard and to make transfer runs between NS and the W&W. This local will most likely only require two locomtives
Hanover Yard:
Hanover serves only the Hanover Sub and as a transfer point for traffic coming down from York. The jobs based out of Hanover are:
HVHG Hanover to Hagerstown road local.
This job is responsible for serving all of the industries and interchange points on the Hanover Sub between Hanover and Hagerstown as well as forwarding cars on to Hagerstown from York. Train returns as HGHV. Due to heavy grades and long train lengths this job requires a minimum of three six axle locomotives.
HVPC Hanover to Port Covington road local
This job is responsible for serving all customers and interchange points on the Hanover Sub between Hanover and Port Covington Yard. train returns the same day as PCHV. Due to grades and train lengths this job usually requires three locomotives.
RKRN Hanover Rock Runner
This job is responsible for running the unit rock trains from the quarry west of Hanover east to the Baltimore area. This can require two to three locomotives depending on train size.
Port Covington Yard:
Port Covington serves the intermodal facilities located there along with being the crew base for all run through bridge traffic. The jobs are the following:
PC-1 and PC-2 Port Covington Yard jobs
These jobs are responsible for the shift of the yard and the intermodal facility. The two jobs overlap each six hours a day and are both 12 hour jobs. Both jobs require two locomotives each.
N89/N91 Port Covington to Enola and return road trains.
These trains are overhead bridge traffic that run with NS run through power so no HYRY locomotives are required. Trains maintain the same symbols in each direction. (These are HYRY symbols not NS symbols)
N88/N90/N92 Port Covington to Hagerstown and return road trains.
These trains are overhead bridge traffic that run with NS run through power so no HYRY locomotives are required. Trains maintain the same symbols in each direction. (These are HYRY symbols not NS symbols)
Market Street Yard in York:
Market St serves the York Sub, Spring Grove Sec, York Ind and the Codorus Ind. The jobs are the following:
MK-1 Market St yard job.
This job is responsible for classifying inbound and outbound traffic at Mark St, Serving customers on the York Sub between Market and Windsor St and interchanging with the ESPN. This job requires two locomotives.
MK615 Daylight York local job.

MK180 Overnight York local job.
This job serves all local customers on the York Sub, Spring Grove Sec, York Ind and the Codorus Ind along with switching Market St. This job utilizes the power from MK615 or MK-1.
EAHV Enola to Hanover transfer.
This job starts at Market St and runs outbound traffic to Enola stopping at Windsor St Intermodal facility to pick up outbound traffic. Job returns south with inbound traffic setting out cars at Windsor St and Market St on its way to Hanover Yard. Job returns to Market St with outbound/inbound traffic from Hanover. This job runs overnight and due to train lengths requires three locomotives (usually MK-1 or MK615's power with an additional standby locomotive.
Windsor Street Yard in York:
Windsor St serves the Windsor St intermodal facility and the Central Sub. The jobs are the following:
WSPC Windsor St to Port Covington road local.
This job serves all local industries along the Central sub as well as transferring intermodal traffic between Port Covington and Windsor St. This job requires two locomotives.
So after reviewing all this the minimum my railroad needs to operate would be 24 locomotives. This would leave the railroad with no backup power what so ever so in reality to provide proper coverage and allow for mechanical issues the railroad would realistically need around 30 locomotives. I have tailored my roster to reflect the operations needs along with sticking to power I have an interest in and that will be believable. I personally am a diehard EMD man myself but I have a soft spot for the old GE U boats hence the power mix.
2 GP10
2 GP15-1
4 GP38-3 (rebuild GP50s)
2 GP40
1 Slug
2 U18B
1 U23B
1 SD38P (ex BN SD35 rebuilt to SD38-2 standards)
1 SD39-2 (SD39 rebuilt to -2 specs)
1 SD40-2R (original SD40 built on SD35 frame)
2 SD38-2 (SDP35s rebuilt to SD38-2 standards)
8 SD50
5 U30C (still unsure of these locos)
I will most likely never have a model of every locomotive as I will most definitely never be able to model every aspect of the HYRY system. I hope that this in some way helps you see what goes into creating a realistic locomotive roster in both size and style of power needed. Any questions or comments fire away.
