MNCR has a catenary outlier fleet, a Brookville outlier fleet, and WOH outlier fleet maintained by NJT. Metra has their electric outlier fleet. Boston T has different rolling stock on each line. SEPTA has an outlier fleet of random motors. Why it would be out of order for Maryland to have an outlier fleet of motors maintained by Amtrak is beyond me. It's pretty normal to have an outlier fleet.
Some things to point out: ...
3) With the WOH fleet the key words are maintained by NJT. Plus those fleets are a mix of new and still-in-good-condition locos that went out for rebuild. Those Pascack Valley and Port Jervis trains are more or less NJT trains with MNR paint. Heck, those MNR units can be seen on Morris & Essex trains.
You make some good points here and I appreciate your logic. Wasn't MARC doing just that - having Amtrak maintain their motors, just like NJT maintains WOH? It worked well until the entire toaster fleet just got old.
Well from what others have said here that is indeed the case. However one thing to further take into consideration is that in the 1980s a number of commuter rail agencies had multiple types of motive power and rolling stock. Today it appears to be all about homogenizing motive power and rolling stock fleets as much as possible WHILE providing extra fleet flexibility as well.
Now in the case of SEPTA they can do EMUs and ACS-64s and MLVs since their network is completely electric so there is already fleet flexibility factored in there. And with replacement of the Silverliner IVs on the horizon at some point who's to say they're not using this "base" order as a way of gauging the Silverliner Vs vs. newer electric locos + coaches.
For all we know MARC could be using this particular Charger order as a test case for perhaps a somewhat larger procurement; even with a relatively new fleet of MP36s. But even if they aren't that still means that they've got only 2 types of locomotives (the others being the MP36s of course; are there any older Geeps still in service/due for retirement?) that can operate on any of their lines.
Perhaps only if plans to go to DE really pick up steam then having a sizeable electric locomotive fleet strictly for the Penn Line will be considered a good investment by MARC.
