These six cars were built for use on the Audley route, where due
to lower passenger traffic, the use of high-capacity bogie cars
was not merited.
The order for these cars was originally placed with Brush Electrical
Co., but as a firm delivery
date could not guaranteed, the order went to U.E.C. Co. Limited
(formerly Dick, Kerr Limited). They were made to a G.F.Milnes design,
at the firms Preston works, and were delivered in July 1907. The
body work was distinctive Milnes style with arched windows
to the saloon, and were officially known as combination
cars being divided into three compartments, each end saloon was
reserved for smokers and had drop-framed windows. Seating in the
end sections was originally for 8, plus standing, but an extra seat
was added upon delivery at Intack. The centre saloon had longnitudal
seating for 22 passengers, over this section a clerestory roof with
small drop-back coloured windows was placed. the platforms were
open and the bulkheads were off-set, unequal width, an oddity of
many Milnes design single-deck trams. There was no door
from the platforms to the end sections, but a removable bar was
fitted at the drivers end to prevent passengers boarding or alighting
at the wrong end.
On delivery they had their trolley poles replaced with dwarf mast
(3ft. high) and a shorter pole. A roller blind destination indicator
box was fitted as new under the roof at each end, and headlamps
were also fitted as new.
Bogies were the same as the Siemens cars i.e. Brill
22E maximum traction and they were fitted with 2 x 37½h.p.
GE 58-4T motors, which made them much slower than the Milnes
cars, a facet which would eventually be their downfall. Controllers
were B.T.H. B18 type. The interiors of the cars were finished in
oak and ash, and the roof lining was 3-ply veneer.

At first glance these cars looked identical to No.s 76-81,
but a closer inspection will show several design changes. Again
built at the Strand Road works of U.E.C. Co. Limited at Preston,
although originally they were re-drawn with three windows to the
central saloon, a very Dick, Kerr trait, but this was changed back
to the original 4-window design on the insistance of Blackburn Corporation
for the sake of standardisation.
The end smokers section were fitted with fixed windows, and to
compensate, for ventilation purposes, small air vents were fitted
above each end saloon window. Instead of the single and double seats
in the end sections, longnitudal seating was fitted throughout.
The bulkheads, though still off-set, were of equal width and a roller
shutter was fitted across the door-way, which could be lowered at
the drivers end, making these cars less draughty than No.s
76-81. The same bogies, motors and electrical equipment was fitted
as the first batch.
Between May 1914 and January 1918, all the single-deck cars were
fitted with windscreens
around the platforms giving them much improved appearance, at the
same time their brake handles were replaced with a vertical brake
wheel. At the time of rebuilding several of the first batch lost
their drop-framed windows in favour of fixed windows, and those
that retained them had them painted ivory instead of the natural
varnished wood.
In May 1925 No.86 was rebuilt, as an experiment, with air-compressor
operated platform doors, fitted on the opposite side of the platform
to the entrance to make the car a front exit-rear entrance one-man-operated
car. At the same time the original motors were replaced with 2 x
50h.p. DK31A motors, and new B.T.H. K3 controllers. The experiment
was unsuccessful, and the scheme was abandoned after about 18 months,
the platforms were rebuilt to their original condition, though the
new motors and controllers remained in the car for the rest of its
existence.
Livery of all the single-deck cars was ivory around the windows
and on the rocker panels with olive green on the rest. The roof
originally painted white, was later altered to dark grey. This was
the only class of tram never to carry the large BLACKBURN
CORPORATION TRAMWAYS title, a small gold shaded title
was at first placed on the sill, or sole bar, and later in the bottom
left-hand corner of the rocker panel. Many of this class of tram
were used for special occasions and were decorated, such as for
Shopping Week and for the Coronation of King George
V.
After the closure of the Audley route in 1935 they were partly
withdrawn from services, being used as tea-time specials on the
Cherry Tree route, but once this section closed, in 1939, they were
withdrawn completely from service and eventually scrapped at Intack
depot. |
