TRS is an independent company.  We are not employed by  an particular manufacturer of gauge 1 trains.  We service all makes and models of gauge one products!

We strive to do the job correct as our priority over deadlines or broken promises.  We do not take short cuts or quick fixes just to meet a time line.

People forget how fast you did a job – but they remember how well you did it.

    CP Hudson upgrades by TRS Shops

    • Boiler-Coal fired boiler with fittings (if the engine is alcohol fired all old boiler fittings are reused, for gas new fittings will be made for blower, etc)-Can be supplied with test records that comply to G1MRA standards
    • Coal bunker- Custom fabricated to replace the oil bunker, modeled on CPR prototype practice
    • Cab modifications-Water feed system overhaul-Front end modifications (not as severe on alcohol fired engines, mainly rearranging plumbing)
    • Ashpan/Grate. -We employ a sliding grate and fixed ashpan to facilitate easy cleaning of the fire after each run, the grate is pulled out and then ashes/clinker are raked into the central ash pan to be dumped from beneath the trailing truck via a sliding door.-No removal of the rear trailing truck is necessary to accomplish this, engine can be cleaned while it is on shed
    • Decals and custom paint Renumbering to any number between 2820 and 2859, which were classes H1c and H1d of the Royal Hudson, these were the only two classes that were both streamlined and coal fired.-The 2860 (what the model is based on) belonged to the 5 H1e class engines which was built oil fired for the British Columbia region (engines numbered 2860-2864)
    • Parts- new steam and water pipes, new blower and exhaust nozzles, axle pump, tender to engine piping, lights-A incandescent headlamp in a custom turned aluminum reflector (powered by 2x “AAA” size batteries), A new front valance as designed by David Leech.  Replacing the inaccurate staggered one on the model with a prototypical full width valance.

TRS IS NOT a factory assembly line business.  Our priority is quality work, not deadlines that might result in the return of a job. While our priority is a proper job over a time frame we can offer an “EXPRESS” service.   Express service is for most jobs that have a time line of 2 weeks to 30 days.  Please note that some jobs have a built in time requirement (e.g. breakdown and rebuild of a large locomotive would be about 25 hours) that cannot be shortened. 

We guarantee and warranty all work done by us (if the work done has any other party intervene then TRS it is voided of any warranty).
