A few months I posted that I noticed that TBOX and FBOX boxcars seemed to be replacing a large percent of the RBLs at tomato processing plants.
Saturday I was in Fairfield, CA, so I decided to stop by the brewery to see if I could photograph any RBLs. I was surprised to find about 90% of the boxcars there were TBOX boxcars.
It has also been a few years since the IBOX prototype was built. The January 2008 ORER lists no production IBOX cars.
It seems that there is a trend to switch from RBLs to plug door XM boxcars. I remember hearing that railroads are reluctant to buy new boxcars because they have a long payback period, or may not ever pay for themselves. Have railroads, TTX, and lessors found that RBLs are not profitable and therefore not replacing them as they wear out? If so, is this causing fees for RBLs to be high enough that shippers are deciding to switch to XM whenever possible?
Can’t disagree with you, Eric; I think it’s been over 25 years since the last RBLs were built (other than that clunky-looking IBOX prototype).
Come to think of it, we usually see the imported Mexican beer arrive at Proviso in RBLs during the winter to keep it from freezing. Not this past year, though–they used the same box cars all winter. (Those exotic old box cars are one of the perks of my job–and I don’t even drink!)
I can’t imagine that plug doors afford that much better temperature control than sliding doors, but most new box cars from the past several years have had them. I would say that if no RBLs come out in the next five years or so, you’re probably right.
RBL=insulated plug door boxcar. Wisconsin southern has quite a few RBLs, and several of these have one of a kind markings, such as the 9/11 RBL, the model railroader 70th anniversary RBL, and the Athearn 50th anniversary RBL Recently, WSOR painted a RBL pink for cancer awareness.
"RB - Bunkerless refrigerator car with or without ventilating devices and with or without device for attaching portable heaters. Constructed with insulation in sides, ends, floor and roof to meet maximum UA factor requirement of 250 BTU/F/Hour for 50 foot cars and 300 BTU/F/Hour for 60 foot cars. Effective for cars ordered new after March 1, 1984. Note: Cars built prior to March 1, 1984, must have been constructed with a minimum 3 in. of insulation in the sides and ends and 3-1/2 in. in floor and roof based on the insulation requirements given in AAR Standard S-2010 or a thickness reduced in proportion to the thermal conductivity of the insulation
“RBL - Car similar in construction to an ‘RB’ type car, but equipped in addition with adjustable loading or stowing device.”
In other words, an RBL is a reefer with no means to cool the load that has a maximum heat transfer rate (or minimum insulation) and is equipped with load restraints. It may have ventilation and/or provisions for heaters.
Carl, perhaps that plug doors are to keep dust and moisture out. How much do sliding doors let in?
I thought that National Steel Car built the TTX IBOX Double-Plugged Door Boxcars a few years ago. I printed out that page because I thought they were a great new version of the Evans Products Double-Plugged Door Boxcars. Now National Steel Car has completely changed their website.
Looks like I was more tired at the time I posted than I thought.
In a magazine like RailModel Journal it was mentioned that sometime in the 1970’s or 1980’s there was a series of Western Maryland RBLs that were scrapped after no more than 18 years of service.
Are RBLs considered “disposable” when compared to other freight car types because they have to always be in great shape or they are unusable?
Sorry for the week-or-more delay (just back from vacation), Eric–truth is, I don’t know, since I rarely see this train (we don’t have to switch it out). If you have a consist from “a few years ago”, I might be able to compare it to a few present-day consists, but that would be just a snapshot instead of the whole picture, I’m sure.
The newest of the SP 50’ RBLs with 8’ and 6’ doors turn 40 this year. Judging from the lack of this car type within the past few years, which once common around here, they must have never had a Rule 88 rebuild. It is a shame to see the end of one of my favorite types of cars.
With Greenbrier box car the railroads have to choose between a heavy-duty plug door box car and a Refrigerated Box Car. There is nothing else listed at insulated.
The Del Monte cannery in Kingsburg used to ship exclusively in RBLs. I went by there a couple of days ago. There were 5 XM/XP boxcars and no RBLs there.
A fair number of the WSOR RBLs are running up against the 40-year rule, and are going away. Not really any in-kind replacements around, so other car types are getting used. Going to be difficult for the canneries that have doors spaced for the RBLs.
ATW 151xxx 50’ hi-cube boxes were used a little while ago, with the proper forklift allowed quite a bit more product in the car. Now some 60’ inside length boxes are being used when RBLs haven’t come back. MET RBLs still show up from time to time as well.
