Delivered in lined green, the speed whiskers were unique in being the reverse of other classes. The thick section was in the centre, above the coupling, and it tapered to become the waist height lining. They had red buffer beams, and initially white cab roof domes. The image shows an ER set (with a Met-Camm) in Birmingham New Street on 27th January 1962 having just arrived as empty stock to form a football special to Huddersfield. Michael Mensing.
In the 1960s yellow panels replaced the whiskers, and the white roof domes disapeared. Such a set is seen in York station in 1969. John Law.
In the late '60s Rail Blue with yellow ends became the standard, as in this image of a set passing through New Mills Central, heading for the Hope Valley line with a service for Sheffield, on 15th April 1973. Andrew J Crowther.
Of the two early rail blue variations, I have found no evidence that the more common small yellow panel version was carried by any member of the Class, but the yellow cab door variety was - see this image on David Ford's Flickr site.
Being refurbished late in the programme, only three sets received the white with blue stripe livery before blue and grey was introduced in 1979. The image shows 52073 with 59707 and 51846 on 02/08/79 at Lancaster Castle Station in this livery. Robert Frise.
Hammerton St set aside a 3-car set for a day for Hornby staff to measure it for their model. This was at the start of the refurbishment period, and their first release was in the white with blue band refurbished livery. The model was an example from the former NER batch, and the only ex-NER trailer carried this livery was 59707.
This livery also saw the introduction of PTE symbols, and the WYPTE logo could be found on the blus stripe on the drivers side of the power car, just behind the cab, the BR logo on the non-drivers side
When rail blue first appeared in 1980, the West Yorkshire PTE branding was carried on the ER sets, such as this on in York station in the early 1980s. Graeme Phillips Collection. On the opposite side would be the BR logo.
LMR sets didn't seem to carry any branding, not even the BR logo. As example is this set seen at Burscough Bridge, Lancashire, calling with a Manchester-Southport service in 1983. Graeme Phillips Collection.
Later on ER sets could also be found without any branding.
This Class 110 with MetroTrain markings is seen at Southport, date unknown. Andrew McConnell. Normally this branding would be carried on both sides of the cab.
