I do not agree with you, these cars easily fit clearances here in South Florida, they ride as good as anything else and they
are new and clean, I hope they stay at least halfway decent over the coming years.
I think this equipment is working out OK on Tri-Rail and I don't think Tri-Rall fell for anything.
If they are able to get parts for them as necessary, I think they will be running for at least a while.

I didn't say they weren't comfortable or ride good. They're excursion equipment so they have to be comfortable. But, I still think they shouldn't have been used for commuter service. Here are some other criticisms straight from wikipedia:

"Criticism
The DMU consists are generally considered more comfortable in terms of seating than the Bombardier coaches they were acquired to replace. However, they suffer from a lack of bicycle and luggage storage that have been a continual source of irritation and complaints from daily and airport commuters ever since the DMU's original prototype phase. Additionally, wheelchair accessibility is compromised by the entrance steps necessitated by the unit's higher floorboards (required to clear the Detroit prime movers). This problem remains uncorrected, despite the acquisition of the new Colorado Railcar rolling stock.

Additionally, operators contended that a single DMU and trailer car are underpowered for sufficient in-service acceleration, and could not effectively negotiate the 40+ foot grade over the New River Bridge without a helper locomotive, thus defeating the purpose of a self-propelled coach. The addition of a second DMU to the two car motor/trailer consist has since appeared to solve the problem of the New River bridge grade, but acceleration still remains an issue in practice. Whether the DMU's prime movers will accept the strain of present revenue operations remains to be seen."

It seems to be that these are serious (and predictable) problems that stress the point that the CRC designs were never intended for commuter rail.

I have ridden the full three car train several times and it did not seem to me that they had any problems negotiating the
grade over the New River at the time.
Two car operation with just a power car and trailer is not possible because the DUM trailer is simply that and has no
controls.
The main obstacle to future operation of this equipment as I see it is the possibility that parts will be hard to come by and
anything like this always will need various replacement parts.
Probably the jury is still out as to the future of this equipment but for now Tri-Rail needs everything equipment wise that will move.

I completely agree, but those criticisms sound very legit to me. I doubt anyone would "make up" stuff like that.

I think these cars are going to be around for a while. When CRC went belly up, everyone suspected that parts would be hard to come by. That might not be the case because very few wear and tear items were made by CRC. They were all provided by outside vendors. When I ran the simulator facility for Metro-North, we built a Genesis cab with no help from GE. The most expensive item was the throttle assembly, which cost almost $10,000. Because the Metro-North throttle was unique, with no dynamic brake section, they were expensive and had to be custom ordered, but were still available. I took the only spare from the storeroom in Harmon with the understanding that the simulator company (Orthstar) would not modify the unit. To this day, Metro-North has never had to replace a throttle in a Genesis cab, but if they needed one, they could take it from the simulator. If Tri-Rail needs to fabricate parts that are not available from vendors, they can probably do so done easily.

For the next installment of my Remarkable Engine Series, I have covered the Alaska Railroad's only bi-level DMU as it is the only one of its kind still in service. I hope you enjoy! :-D

Well, this video somewhat includes Tri-Rail's DMUs as well as Alaska Railroad 751 since they're both from Colorado Railcar, even though this is posted in the Florida thread.

This spare parts problems needs a different approach by buyers of rail equipment. All contracts need a clause that seller will provide parts for a set time. Wham that time is up builders either will continue providing parts or give all the drawings and tooling to build parts to operator. That proviso will also apply to all parts suppliers. For parts to more than one operator one will be required parts to other operators. Probably can have reciprocal agreements between operators.

CRC is a long dead company now,,best bet is to turn the remaining cars into coaches/cab cars,then call it even cost wise

I believe they would be better off selling these DMUs to Alaska RR, assuming the Alaska RR wanted them. Then with the cash from the sell, buy more double decker coaches from whatever brand they want.
Whereas I doubt Alaska RR would want them for long distance services, they could use them for shorter distance services, especially south of Anchorage.
