Nice weathering!

Those look really nice, not overly done! I like the spillage.

Very nice.  Can we see a

Very nice. 

Can we see a tighter shot of one?

Tighter shots

@Deemiorgos: The link has additional photos of the tank cars.  I may add additional shots as I get to the rest of my GP20 fleet.  Since they were so common in the early 1980's I will have a sizable fleet to service northern Manitoba.

Marc, Very nice! I just saw

Marc,

Very nice! I just saw them on the blog.

I'm tempted to get one for my 74 collection, but will have to figure out, which one would be appropriate for that year.

I can't see the markings

I can't see the markings (COTS label) on this car of yours. Would this one be appropriate for 1974?

both cars were built in 1973

COTS for Procor UTLX:

COTS for North American NCTX:

Either should be good for 1974 and would both be relatively new so likely very little weathering.  My cars are around 8-10 years old in my era so are starting to show some age but still not total rust buckets.  Many of the Procor cars got semi-regular paint jobs so stayed in relatively good condition.  Some dullcote and roadgrime and you should be good to go.

You shouldn't paint freight cars white

Another LPG tank car for the fleet.  Pretty much every white car eventually looks like this.

Thank you so much Marc. I'm

Thank you so much Marc. I'm going to get one.

BTW, I see Atlas now has the True Line Trains 6 and 12 hatch slab side covered hoppers in CN noodle. Are any of these accurate in regards to paint colour and numbering. I recall someone mentioning some are not right; I don't know if this is true.

I'm wondering if this one is:

Atlas/TLT hoppers

They are generally correct for CN including the noodle scheme you have the photo of.  Some small details like the rivet pattern and air reservoir orientation can be different between various car orders but they are pretty close.  CN had 12, 8 and 6 hatch slabsides with both closed and open side sills so should be close for most orders.  Some cars had pneumatic fittings on the bays, others had modifications over the years.  http://www.nakina.net has a good summary of the various car orders.  

Marc, Thanks for the prompt

Marc,

Thanks for the prompt reply. I think this car will be good for my 1974 collection. It says BLT 12-53 and P-U 6-67.

I'll put a ACI label on it. 

BTW, what are those white dots on the side? Would they be on there in 1974?

Reflective dots

CN had reflective dots on their freightcars, not sure about when they started but probably by early 1970's.  You should be fine with them as is.

Thanks MarcUnder notes for

Thanks Marc

Under notes for 355 series cars it says: x113395-113544 series /67-9/72.

Does this mean this car was numbered in the 113 series from 1967 to 1972 then after 1972 was renumbered to 355 series?

BTW, you nailed that weathered white look.

Renumbering of the slabside fleet

I believe (subject to correction) that CN renumbered the slabside fleet from the 113XXX series to the 355XXX series between 1967 to 1972; it took that long to get them all done.  There was a sizeable fleet renumbering carried out in that time frame.  If you want to make your head spin take a look at the 40 foot boxcar fleet renumbering over the years.  I try to work from photos as the mishmash of different car orders into the same number series makes decifering specific car histories very challenging.  

Marc, Good to know and I'll

Marc,

Good to know and I'll check out fleet renumbering over the years on box cars.

Thanks for your help. I'm now going to order the tank car and hopper.

CN renumbering

Marc is correct. Starting around 1966-67 CN began a massive fleet-wide renumbering that among other things moved all hoppers (open and covered) into the 3xxxxx series. The cars were originally in the 113xxx series and moved to the 355xxx series in the late 1960s as part of this effort.

After the renumbering effort, the 1xxxxx series was reserved for gondolas, 2xxxxx were refrigerators and insulated cars, 3xxxxx were hoppers, 4xxxxx and 5xxxxx were boxcars, 6xxxxx were flatcars, 7xxxxx were automotive related (autoracks and parts boxcars), 8xxxxx were stock cars and wood chip cars. 9xxxxx and 5-digit number ranges were reserved for work equipment.

Reflective Dots

According to my notes, 1974 this became Canadian requirement, so it applies to other Canadian railways as well, not just CN.

These reflective markings could be 4" circles or diamonds.

Chris van der Heide,

Excellent

Excellent job!

A bit of variety

This tank car got a few washes with light and dark rust to get the light brown-black colouration you sometimes see on older tank cars.  I may still add a bit of road grime, we'll see how this one sits with me in a few days.  These cars were around 8-10 years old in my era so they were somewhat weathered but not rust buckets.  Plenty more to come, getting on a roll with tank cars.  

Marc, Very nice. How many

Marc, 

Very nice. 

How many tank cars did you get? Any QC issues with any of them?

I ordered one and look forward to getting it. I will have to research what one would look like weathered after 15 months; basically expose to one winter.

GP20 fleet

So far I have seven cars (1 NCTX and 6 UTLX) with another 6 on order from my local hobby shop.  I may pick up more as time goes along.  These were by far the most common tank cars on the Hudson Bay Railway so I'll need a fleet to supply the north. 

So far no QC issues that I have noted, fit and finish are pretty good.  I am swapping out the factory couplers for Kadees which requires a bit of filing on the rear corners of the couplers to clear small tabs in the corners of the coupler box.

I'm now on a tank car weathering binge, currently at 10 cars done out of my 40+/- tank car fleet.  

Marc, this is good news. I

Marc, this is good news. I have had some major QC issue with some of their rolling stock so am pleased to hear about the fit and finish.

So look forward to seeing the fleet of them.

Weathering Tank Cars

Looks Great!    But we need closer shots!  Way too far away!
