⑨Pyewipe Road: (4m 19ch) This BR Eastern Region Type 16a box opened around 1958. According to the Signalling Record Society, there appears to have been a previous box from 1948 until 1958 but not necessarily at the same location and there seems to be uncertainty over the dates. Pyewipe Road box now breaks up the single line section of the former Light Railway. It is a rare example of a block post on a single line with no passing loop [Carrick-on-Suir (Waterford - Limerick Jn) and Midge Hall on the Preston to Ormskirk line are others]. It works by Electric Key Token to Immingham East and by Acceptance Lever to Great Coates No1. Of the 20 levers in the frame, just four are now operational: Up and Down home signals, the acceptance lever and the Gate Stops lever for the level crossing.

The crossing has four gates and the box has a gate wheel but it has not been used for many years and is disconnected from the gate rodding. Instead, the gates are hand worked and co-acting, using part of the original gate rodding, such that when gate one is pulled or pushed, all gates move simultaneously. The gates are not of equal lengths, being split roughly ⅓ to ⅔ across both the road and the railway. This is geometrically necessary to allow the gates to pass each other when swung simultaneously, given the quite sharp angle that the railway intersects with the road. The name Pyewipe Road refers to a former road that used to parallel the railway here; the level crossing itself is on Gilbey Road.

The now disconnected Railway Signal Company gate wheel is maintained in an immaculate condition. It is a very different design to those at Goxhill and Oxmarsh, with the rotation of the wheel directly driving a horizontal rotating shaft which in turn used to operate a gate lever to move the gate rods.

There used to be a number of private siding connections along the single line between Pyewipe Road and Immingham East. These were accessed by Ground Frames (GF), released by the Key Token for the section. Indeed, this may well explain why this section retains token working, while Pyewipe Road to Great Coates No1 is track circuited. All the connections are currently defunct, the last one - Tioxide UK GF (4m 06ch), OOU for many years, 13ch west of Pyewipe Road - was removed in 2022. However, there is a distinct possibility of new traffic at 'Freight Terminal Siding' (0m 18ch) at Immingham East.

⑩Immingham Token Exchange Point (TEP): This was our tenth and final location. This portable cabin type structure opened in 2012 as a full signal box containing an NX panel controlling the Immingham East Jn area. The box was known as Immingham East Junction and replaced the original box of that name, which had a BPRSCo frame similar to Immingham Reception Sidings. That was situated at the junction itself, just over a quarter of a mile northwest of the modern-day TEP. (See BLN 1429.1709!)

In 2015, control was transferred to York ROC with resignalling and the box was downgraded to a TEP only: Immingham Token Exchange Point. Like Pyewipe Road and Great Coates No1, it is only staffed on the rare occasions when a train runs along the Grimsby Light Single (GLS). All other movements through the junction (to the much quieter east side of Immingham Dock) are signalled by the ROC.

The original NX panel was replaced with a much simpler IFS panel; the only other signalling equipment is the traditional token machine for the line to Pyewipe Road. On the panel itself, the only function needed for normal working is Slot IE1 which releases MB4112, the York starting signal to the GLS.

For westbound movements leaving the GLS under normal conditions, Immingham TEP does not use any signalling controls other than the Key Token instrument. When the train arrives complete, the signaller simply returns the token to the instrument and sends 'Train Out of Section'. However, in common with most surviving Token sections (and Absolute Block Sections), it is a requirement for the Distant and Home signals at the exit from the section to be showing caution and stop aspects respectively before a train can be accepted and a token released.

This system is referred to as Normal Contact and Home Normal Contact (NC/HNC). For westbound movements from Pyewipe Road, this means that York ROC MB4111 and MB4113 signals must be showing yellow and red respectively before Immingham TEP can accept a train from Pyewipe Road. In case of a lamp or TPWS failure on either signal, Immingham TEP panel includes overrides to allow a token to be released. Finally, Immingham TEP also supervises three automatic crossings (two AHBs and one AOCL). Indicators (but no controls) for the AHB crossings are provided on the panel.

We were reunited with the other half of the group in the car park at Immingham TEP, where the organiser Nick Garnham and our hosts were thanked for a superb and fascinating day. Our visits raised £1,056 for Gary and Doug's 'Team MOM' effort in support of the Railway Children charity. The team also took part in the 'Three Peaks By Rail' event and their total currently stands at over £11,000.
