Local Freight flows remembered - The “BOC tanks”

The distinctive white “BOC tanks” were a familiar site most afternoons locally as a class 81-5 (roarer) normally returned

the empties from Wembley to Widnes. Services began in late 1970 and at the time these trains were the first

company based trains in the world to carry liquefied oxygen and nitrogen at cryogenic (low) temperatures of

around minus 190 degrees C. The 60 foot long Glouester Wagon works bogie tanks were built with both inner and

outer shells with powder insulation between them.

A fleet of 30 tankers worked the three prime flows from BOC’s Widnes plant (nr Ditton) to Broughton Lane (Sheffield),

Wolverhampton (LL sidings to East of station) and our Wembley North flow.

The up loaded tanks had to run ahead of the morning rush because of the complicated shunt at Wembley. Because the 2

BOC sidings were not wired a surplus ferry van or flat van was used as a barrier truck in shunting.

RM advises “it must of been some shunt to position those BOC tanks, the loop at Kenton

where Sainsburys is today long gone, but the tanks would have backed off the up slow into the complex using number

one ground frame. As no run round was possible the train loco would then run up to Wembley Central, use another ground

frame to cross to the down slow, then run back to North Wembley and ground frame two would be opened to allow access to

the north end. The tank train then being split and positioned on the two company sidings. The BOC terminal was served by two ground

frames known as Wembley North No 1 gf (onto up slow) and No 2 (up slow/down slow) and quite a bit of shunting required to get the tanks

onto the two company siding, the train having to be split. Part of the service line between these two ground frames still

exits next to the overhead line neutral section

Note it was not possible to go from up slow straight into the siding and exit was to down slow only thanks to the interlocking.
Not the easiest locos to 'shunt' with AC locos and I mentioned memories of some sort of international ferry van used as  a barrier wagon.
Departures heading north ok but the two portions of tank wagons needed to be shunted together prior to departure”.

The empties returned North early afternoon but by 1985 the main flow was switched from Wembley to Ipswich and diesel

haulage in a late evening down slot made the train less memorable as you can’t beat an 82 roaring North in warm afternoon

sun with 10 “white tanks” in tow.

More “BOC” bits

85 015 working a Manchester-Willesden Freight had a rear end collision in bad weather at Roade cutting with the BOC tank train.

“I used to cycle over to watch this train as it was always a big roarer! In fact I scored my last 82 for sight on this train”

82008 on the up BOCS in trouble when a “journal” burnt off a BOC tanker damaging over a mile of track near Hemel in Jan 80

In atrocious weather on 140880 85015 on the 2157 Dewsnapp-Willesden collided with rear of the 0116 Ditton-N.Wembley BOCS. 2 BOC tanks were damaged as were wagons on the freight and 85015 received severe front end damage and spent several years in Crewe Wks being rebuilt. The collision just South of Roade closed the Northampton loop for 2 days

Today’s scene

A small non rail served BOC depot remains at Wembley North but the main former BOC rail depot area is now

a warehouse. The BOC facilities incl the unloading bays and holding tanks were demolished in Aug 88. Relic sections of the up service line between the old ground frames survive, as does, incredibly,

a sign stating “electric trains must not enter BOC sidings”
