Begin/End CTC Romford

Our big push for the Doubleheaders Tour this past March was to finally fill in the scene at Romford ON, the junction where the Parry Sound Sub from Toronto joins in to the Cartier Sub. This finally enclosed and hid the helix we had built in this corner of the layout that carried the tracks from the Parry Sound Sub staging yard to the upper level deck where Romford is situated. But really the scenery was just roughed in at the time, and many more details were required to finish the area. Our upcoming Fall Open House has provided us with a cause to continue the scenic efforts from here further down towards Coniston ON (diamond crossing with the CN Bala Sub), and to populate Romford with more details.

Being a mainline junction, Romford was a controlled interlocking. In the 1970s Centralized Traffic Control (CTC) governed train movements over the Cartier Sub from this point (mileage 72.4) eastward to North Bay ON (mileage 0). Westward for the six miles between here and Sudbury, the Cartier Sub was double-tracked with Automatic Block System (ABS) signals protecting movements in one direction only (right-hand running). The Parry Sound Sub travelling south was single-track ABS territory. Because the CTC section began, or ended (depending on which way you were going) at this interlocking, dispatchers would refer to this spot as ‘Begin/End CTC Romford’.

Beyond the obvious signals, real life interlockings are filled with all sorts of trackside details such as large signal bungalows, relay cabinets, battery vaults, electric switch motors, and if you’re railroading in Canada; switch heaters, and associated fuel tanks. With this in mind, we felt further enhancement of this scene should be done before our next open house.

Signal 724 and its companion dwarf signal, along with a GRS model 5H dual-control switch motor, an oil-fired switch heater (it gets very cold here in winter), and signal relay cabinet. The old-school switch stand here guards a storage track, which is obviously controlled manually by crews.

We are still waiting for the actual station to be completed, along with a custom-built cantilever signal bridge that is required to elevate signal 1217 over the Parry Sound Sub (both are in development). But in the mean time with telephone poles added, more vegetation and ground cover, and all these interlocking details, we are at a level where Romford can almost be called complete.

Guarded by signal 723 (westward signals are odd-numbered, and eastward even) this area of the junction is full of assorted CTC details. The Parry Sound Sub to Toronto is the line curving to the south here. A cantilever signal bridge that governs this line will be added in the future.

Not just CTC details, we’ve also finished off the swamps surrounding the Parry Sound Sub’s approach into Romford. Oh, incidentally, don’t drink the water here.

We’re starting to get excited about the open house, and wanted to share these photos of our progress. There are many other additions and improvements we’ve made since the Doubleheaders Tours this past spring, let alone last year’s open house. All of this will be here for you to explore this Saturday October 14th. Hope to see you there.

 

Signalling the Sudbury Division

Since our club’s initial decision to model the CP Sudbury Division in the 1970s era, it was understood by the membership that at some point railway signals would need to be installed on the layout. Not only did we want our layout scenes to look close to their real place counterparts despite having to selectively compress them, or operate equipment that appeared just like what really ran through northern Ontario in the ’70s, but we also wished to operate the layout in a realistic manner too.

The CP Cartier Subdivision between North Bay and Cartier was all CTC (Centralized Traffic Control) territory during the 1970s, with the exception of the six mile double-track section between Romford and Sudbury yard which was ABS (Automatic Block Signal System) signalled in one direction for current of traffic. Regardless of the two signalling methods it meant the club’s entire east-west mainline was protected by signals, and therefore we would need to duplicate this if we wished to achieve our goals of both looking right, and running right.

That said, we can report that signalling a model railway is very much more easier said than done. However after 20 years of planning, and of delaying a lot of scenery work from being started due to the wiring and complexity of the project, the 1/87 scale Sudbury Division is seeing its first signals begin to sprout around the layout.

Temporary dual-head and permanent dwarf signals installed at Romford. Once fully programmed they will protect this busy junction just like their real-life counterparts.

Though much of the hobby has progressed quite dramatically over the past 40 years, sadly the process of signalling a layout has lagged behind despite the pioneering efforts of Allen MccLelland’s V&O, or Bruce Chubb’s Sunset Valley back in the 1970s. Yes, there are multiple sources of hardware available, and JMRI (Java Model Railroad Interface) software is free, however none of this is really plug and play. You need to program signal scripts and modify JMRI for any of this to work. Between knowing where the signals need to be installed, planning and wiring the signal blocks accordingly, selecting the detectors, switch and signal controllers and then programming it all to work, there is one other big problem for us. No one out there offers ready-to-run Canadian-style searchlight signals.

Though searchlight signal kits do exist in HO scale, they are US-based and need to be disassembled and pretty much scratch-build to have them appear like the real deal did. This and both CP and CN did have some differences in their ladder assemblies. For this reason, the WRMRC has decided to build their own, and to use temporary signals in the meantime. But it sure would be nice if a Canadian model manufacturer considered reproducing them for HO modellers at some point. Hello Rapido; wink, wink, nudge, nudge!

Westbound signals guarding Romford. The mainline is on the right. The wye tracks to the left connect with the Parry Sound Sub to Toronto. The track in the middle is a set-off siding.

There is also the little wrinkle of the dispatcher needing a CTC panel for this all to work. However the good news for the WRMRC is the CP Cartier Sub was signalled in the 1960s, and thus never used one of the ‘classic’ CTC panels that railfans usually imagine. CP had their own hybrid system housed on the second floor of the Sudbury Division HQ building, featuring a large white wall panel with a black trackage schematic, and yellow lights displaying track occupancy. The dispatcher set switches and direction of traffic with a keypad assembly. Frankly, this sounds a lot like something you can duplicate on a computer screen and controlled with a keyboard, and so that’s exactly what we will be doing.

Temporary dual-head signals protect the CP Cartier Sub diamond crossing with the CN Bala Sub at Coniston, Ontario. The diamond, much like our signals, is a work in progress.

Regardless of all these difficulties, the WRMRC has a small team working on the project and they’ve been making great strides recently. As you can tell from the photographs, the layout is already looking dramatically different. We look forward to the day we can ‘un-bag’ these signals for a future operating session, and have our engineers operate their trains as per signal indication. This also means scenery can progress in these areas too. The WRMRC’s goals of ‘looking right’ and ‘running right’ are slowly being achieved.
